Althoughonly in 1 ~ 2 shoulder straps and place the bag items, the combination of the"bag", but according to different mountaineering purposes, the diversityof design concept, the complexity of the backpack and equipment have some, youneed to spend time, flower heart to understand, of course, when you find yourideal backpack, that kind of joy and satisfaction, will be accompanied by afuture every outdoor journey.

use affects design

Amountain backpack is one of the most important equipment for climbers. It musthave a large capacity to pack all the food, clothing, and household belongingsin the mountain. It must also be able to provide the user with comfort in thelong term, and not cause overwork or back pain due to overloading.It is veryimportant to carry the backpack's center of gravity close to the body, toreduce the risk of losing foot due to the unstable center of gravity of thebackpack;And they are less hindered in moving through the bushes.

Inthe design of hiking backpack, the main consideration must be the largecapacity and comfortable bearing, which must have the followingcharacteristics:

1.SuspensionSystem: the current HDPE back version or metal frame design is used as the mainframe of the Suspension System. A good Suspension System must be able to evenlydistribute the weight of the backpack to the user's back and waist.

2.Hip Belt system (Hip Belt) : well designed Hip Belt, not only fit comfortable,and can effectively distribute the weight of the shoulders

3.Ventilation system: bags that are in close contact with your back for longperiods of time can cause back moisture and discomfort if the Ventilationsystem is poor.

4.Attachment system: the strap system of the backpack is designed to be simpleand practical, mainly including the strap for sleeping pad, ice axe, cramponsand mountaineering poles, plus the necessary strap for the backpack.

5.AccessoryPockets: the necessity can be considered according to the user's needs.

6.Water bag Compatibility: with the increasing popularity of the straw water bagsystem, the Compatibility of the bag itself with the water bag becomes more andmore important.

Atpresent, there are several main grades of mountaineering backpack on the marketof mountaineering equipment:

1.Simplicity: this type of backpack only has a simple main bag and straps,without any design of carrying system or bracket. It is mostly used for smallbackpacks for one-day trips.

2.Lightweight: this series of backpacks take lightweight as the main designconsideration, and will use thinner and lighter fabrics. Most of the backpacksonly have a fixed version of the carrying system, and cannot adjust thecarrying system.

3.Durability: many traditional inner backpacks belong to this type. The backpacksthemselves have a complete and adjustable carrying system, and are attachedwith a lot of sponge padding to increase the comfort of carrying;The choice ofknapsack cloth also gives priority to with wear-resisting massiness, butknapsack itself "empty weight" too heavy is its shortcoming.

Accordingto the capacity of the backpack liters, the backpack is divided into small,medium and large three levels.

1.Small backpack: with a capacity of less than 35 liters, most of them are mainlyone-day hiking trips.

2.Medium backpack: between 35 and 55 liters, suitable for overnight trips, or for3-5 days of mountain activities after lightweight equipment.

3.Large backpack: with a capacity of between 55 and 75 liters, it is generallyused for long days of hiking on high mountains.

4.Oversized backpack: the backpack has a capacity of more than 75 liters and issuitable for mountaineers with special needs, such as mountain photography, long-termoutdoor ecological research, or snow and ice climbing activities.

carry the system big analysis

I.What is a burdened system

Backpackto the whole can put stuff back bag as the main body, but need to be able towalk back in the body comfortable, you must have a suitable bearing system,bearing system in simple terms, is the main backpack to make simple duffel bag,combined with the body of a device, so for most inside frame backpack, broadlyspeaking, it contains a combination of the shoulder belt and belt system, toreach a place the luggage main bag, with the upper body perfect unifies intogether;An excellent carrying system enables the user to keep the backpackclose to the body's centre of gravity and distribute the weight of the backpackevenly over the shoulders, back and waist while climbing up and down the hillor in various climbing activities.

II.Different USES have their own exclusive design

Fromthe simple design of two sets of parallel aluminum strips in the early stage,to the design of cross strip and hard back version, each brand has a uniquepatent, which is described as follows:

1. The aluminum support: the first straight type include backpack, is thealuminum bar with two parallel, insert the backpack behind a particular track,and complete simple bearing system, the two aluminum bar called the backpackstructure and appearance, carry on also formed a very good sense of support, atpresent a lot of labels remain the traditional design.Some manufacturers havealso changed the structure of the aluminum strip to cross the design, no matterwhat, the aluminum strip must cooperate with the curve shape of the human bodyback bending, in order to ensure the comfort of the burden.

2.The back support: the design of the backpack is incline to lightweight, somanufacturers obsessively pursuing, looking for a more lightweight supportmaterials to HDPE as raw material, soft hard moderate, and can be bent with thebody back, like this was developed as a bearing system, lagging although feelsa aluminum bar support hard, but with proper foam and cooperate with the backof the human body modelling design, can be said to be very comfortable withsystem.

3.Frame support: when the carrying system meets the basic demand for stabilityand comfort, we begin to think about how to avoid the sultry feeling ofcarrying the back for a long time, and the frame-based carrying system is thusdeveloped;The carrying system of the frame usually USES the outer frame ofmetal or plastic material. At this time, the space in the middle can be used asa cool back ventilation room, and the gap can be used to convection with theoutside air, to reduce the sultry feeling when carrying.

4.Whether or not there are adjustment functions: many backpack carrying systemshave adjustment functions to change the suitable back length of the carryingsystem by moving the upper end up and down with the contact point of thebackpack;A lot of more advanced knapsack, pay attention to the characteristicthat is tailor-made like clothings, carry a system according to different backlength, cent S, R, L 3 kinds of size, just be like the small, medium, big sizeof dress, will adapt to the person that bear different figure, and theadjustment function that designs to carry a system no longer.

III.Lightweight bearing system

Because the world equippedwith lightweight, currently on the market, there are many lightweightbackpacks, traditional 60 ~ 70 litres of empty backpack major is about 2.5 ~3.0 kg, and the same capacity of lightweight backpack will empty down to 1.0 ~1.5 kg, in addition to the weight of the fabric material itself to streamline,is partially by sacrifice part of bearing system comfort.Lightweight backpackdesign principle, the main is based on bag packing lighter weight, so most ofthe backpack has carried weight advice and limit, if the weight of theequipment of the average person, has yet to reduce to suitable for lightweightbackpack weight range, go buy lightweight backpacks, often don't feelcomfortable, bear system for the backpack so, circulating in the equipment oflightweight world sentence is: "backpack is equipped with lightweight,finally need to replace a" equipment, can be said to be the words ofwisdom.Lightweight backpack, because of the burden lighter in weight, so thedesign of the bearing system is relatively simple, the use of HDPE back, or ahard the whole piece of foam back to, to pursue extremely lightweightbackpacks, bearing system may be only two shoulder with a belt, back issupported only by the use of sleeping mat rolled up around the backpack, tosupport the effect of the backpack, also can saying is a lightweight utilityconcept of play.

experiencethe feeling of unity - correct adjustment

I.selection of backpack size (shoulder strap, belt)

Atpresent most of the large capacity backpack, there is shape design for users ofdifferent size, to adapt to shouldering height or size of different shape,volume smaller backpack (less than 30 liters), because the backpack itself capacityis small, can bear the weight of the light, the size difference for backpackcomfort is affected, so usually won't segment size.Bag size selection shouldpay attention to the following procedures:

1.      測量正確的背長：背負系統主要是針對不同長度範圍的背長來設計，一般以英吋為單位，14”~18”是屬於「短背長Short」，18”~21”是屬於「標準背長Regular」，大於22”則是屬於「Long長被長」，也有些廠牌以S、M、L來做分別，國內廠商進貨大多是以標準背長為主，如果身材矮小的人背負起來會不舒適。不同的背長尺寸也會影響同及背包的容量，雖然差異不大，但是購買前必須了解清楚，以免因選擇較小尺寸而無法滿足容量需求。

2.      肩帶尺寸：對於肩帶尺寸，主要丈量的依據是胸圍的大小，跟購買上衣時選擇尺寸類似，例如如果平常穿著S尺寸的上衣，則肩帶也可以選擇相近尺寸。不同廠牌之間的尺寸會略有差異，所以最好向國內的代理商詢問清楚。

3.      腰帶尺寸：腰帶尺寸與腰圍的尺寸息息相關，尺寸太小時腰帶的襯墊會不足，尺寸太大時則無法完全束緊，各廠商間會依照不同腰圍分為S、M、L、XL，有些廠商還會配合個人腰圍身材，進行量身打造的熱塑定型。

二.測量你的背長

不論您選擇任何廠牌的背包，要購買到合適自己身材的尺寸，最重要的關鍵就是測量自己的背長（Torso Length），因為背長測定依據的脊椎骨是隱藏在體內，所以必須遵循依定的步驟，才能精確測量到正確的尺寸。

1.       兩腳分開與肩同寬，身體垂直站立。

2.       將兩手以插腰的形式放置於腰部，頭則微向前彎。

3.       請他人利用軟尺從頸部最突出的骨節（約在肩部與頸部相交的最高點），到插腰的兩手拇指端連接線中點，所測量的長度即為適用背包的「背長」。

4.       依照所得到的背長尺寸，提供給背包銷售的經銷商，作為選擇合適背包的參考，然後經過實際試背來作為最終選擇的決定。

三.背包的調整方式

一個設計精良、適合自己身體尺寸的背包，還必須經過適當的調整，將肩帶、腰帶、背長調整到合適的位置，才能將背包的性能發揮到極至，通常而言，愈是設計精密的背包，所需要調整的部份也愈多，如果在使用前沒有調整好，背負時會產生十分不舒適的感覺。背包調整必須依照一定的程序步驟，來束緊相關繩帶：

1.       選定合適背長尺寸後，許多廠商還有寬肩或窄肩版本的設計；有些廠牌則是可以依個人肩寬尺寸選定調整。

2.       將所有與背負系統相關的調整帶放鬆，然後將兩手穿入肩帶（Shoulder Straps）之中。

3.       先暫時扣上腰帶（Hip Belts）及胸帶（Sternum Strap）。

4.       將肩帶下拉調整到舒適的位置。

5.       將肩部寬減帶（Load Lifter Straps）向下拉緊，此時肩部寬減帶與背包連結的部位，須接近肩帶的最高點高度或稍高。

6.       重新調整腰帶（Hip Belt）的鬆緊度，並將腰帶旁的穩定帶束緊。

7.       Make sure the tightness of each fixed belt is appropriate.

packingadvice for backpacks

Boughta good backpack, if you do not know how to fill skills, not only will cause theburden of uncomfortable, but also will not be able to put all the bags, and cannot give full play to the performance of the backpack.A well-packed backpackwill look neat and crisp, while a bag with poor packing skills will lookdistinctly lopsided or have a center of gravity tilted to one side.

I.The center of gravity of the backpack

Thebasic principle of packaging, according to the location of the center ofgravity, will produce different feelings of carrying;Generally speaking, thecenter of gravity up is conducive to carrying comfort, the center of gravitydown is conducive to balance and stability., however focus on or next, placethe weight in close proximity to the area of the back of the body, is not thebig principles: (1) focus on partial packaging: this method had manyadvantages, such as with comfortable, but in walking the wall caving and otherdangerous precipice terrain, center of gravity requires extreme balance, tendto have a center of gravity be unsteady problem.(2) the packaging method withthe lower center of gravity: for the passage of dangerous terrain, thepackaging method with the lower center of gravity is conducive to the balanceof the center of gravity, but the burden is easy to cause discomfort.

II.Backpacking method

Basicallyin the outdoor hiking, can use the filling method and order, can use thefollowing basic principles and steps.

1.For bulky equipment, first consolidate the bottom of the backpack: put thesleeping bag and tent tent inside and outside (the camp pillars have beenremoved and placed separately) into the bottom of the backpack.

2.Strengthen the middle and lower layers of the backpack with warmth and changingclothes: prevent the water bag from being put into the backpack after storage.

3.Middle and lower space to fill food: there are still some space in the middleand lower layer of the backpack, so the food can be divided into heavy staplefood and other miscellaneous food;Food should be pre-packed into a number ofsmall bags, which can be filled with gaps.

4.Weight placement to left and right balance: must maintain the principle of leftand right balance.

5.The heaviest items are placed in the upper middle and back areas, such asphotographic equipment, gas canisters and staple food such as rice noodles.

6.Frequently used equipment is placed on the upper layer of the backpack: thinlong sleeves or vest, and the most important raincoat and rain pants can beplaced on the upper layer of the backpack or the outer pocket, which can bequickly obtained in case of sudden rain;The top bag usually has a hat, snacks,headlamp, and kettle for easy access.

7.Packing skills of POTS and pans: POTS and pans belong to the equipment withfixed volume, which is not easy to compress or twist. Therefore, they must beplaced on the upper layer of the bag as far as possible.

8.Pack on both sides of the backpack: the straps on both sides of the backpackcan be used to tie the narrow and long pieces of equipment such as sleepingMATS, umbrellas, hiking poles, or tent poles.

knapsack material and design trends

I.Common materials for backpack fabric

Earlybackpacks were mainly heavy and water-absorbent canvas. Later, nylon cloth wasalso widely used in backpacks. However, it was the appearance of high-strengthCORDURA fabric that really changed the history of backpacks.CORDURA fabric isdupont patent products, mainly is the use of nylon yarn as raw material,through the unique high density weave, and form the special wear-resistingmaterial, lightweight, quick drying, soft, abrasion resistance, tensileproperties, general with Danny number (Denier, referred to as D) as a standardof strength, the higher the number, material strength and abrasion resistanceis better;The design of general knapsack, mostly in the bottom that is easy towear and bear larger force, use the cloth with higher Denny number, the more tothe upper layer, bear smaller force, the cloth that use Denny number is loweralso.The Denny number calculation method is based on the weight of cloth fiber9000 meters long, which is the measurement basis of Denny number. For example,the fiber 9000 meters long and net weight of cloth is 600 grams, then the wovencloth will be called 600D.The inner layer of the CORDURA fabric will also havea waterproof coating to achieve the initial waterproof purpose of the backpack,but there is no guarantee that the backpack is completely water-proof, so it isbest to match the waterproof bag inside the backpack to prevent the equipmentfrom getting damp.

II.The new trend of backpack design

From the early military canvas bags, thehorizontal large backpack in the early stage of baiyue development, thealuminum frame handed over from the United States, to the era of straight innerframe backpack innovation, the backpack can be said to have experienced manygenerations of succession, before becoming the mainstream of today's model.In theshape of the straight backpack, many new concepts have been introduced inrecent years. If you don't want to buy LKK or out-of-season products, these newdesign concepts are worth knowing.

1.With the high development of lightweight outdoor fabric technology, it is nolonger a distant dream to obtain a new generation of lighter, thinner andstronger backpack fabric. Therefore, most backpacks will follow the concept oflightweight to pursue a lighter backpack with the same strength and capacity.

2.Waterproof traditional backpack car sewing, will not go through specialwaterproof processing, and water is easy to infiltrate into the backpack inrainy days and get wet equipment, a new bag of backpack has been completelywaterproof style, waterproof zipper is also widely used, is like the Gospel ofoutdoor activities on the water.

3.Heat dissipation and permeability backpack except good back back back if notventilation, whole day activity, ensure back sweating, so each brand has aunique patent at present, on the back of ventilation design, also some specialstyle will emphasize on perfect air circulation system, especially afraid ofhot friends can be taken into consideration.

4.Simplify the traditional backpack design, will tend to design a variety of straps,currently due to the lightweight design concept, many bags only retain the mostimportant strap system;Other backpacks are lightweight by omitting the top bag.

5.Refinement of the carrying system the current design of the carrying system istowards a very diversified and refined, in addition to a variety of back sizesfor selection, shoulder straps and belts can also be customized according tothe shape of the user.The system can also be fine-tuned for different backlengths and shoulder widths.

6.Compatible with water bag and matching with hiking friends to use a largenumber of water bag and straw system, many backpacks will be newly designedwith water bag and straw compatible with the opening and inner bag, convenientto use with water bag.

7.Overthe years, the design of mountaineering backpack tends to the design concept ofpersonalized commodities more and more, with special shape, color and pattern,to highlight the individual or brand's unique style, back it, you can recognizeits unique style.

When buying a backpack, you must first decide how much you want to buy based on howyou spend your time outdoors and how many days you expect to spend.

The capacityof a backpack is determined by the volume of the contents of the backpackitself, usually measured in liters.In addition, also have to choose to suit hisbackpack, can give full play to the backpack itself has the function, the Sizeof the backpack is suitable for individual body length, mainly back long Torso(Size) to determine;At present a lot of knapsack design, still can havedifferent carry a system to deal with all sorts of different carry a weight,understand the weight that wants to carry in oneself activity beforehand so,can choose appropriate carry a system more accurately.

1.One-day trip: generally, you can choose a 20-liter backpack for a 4-5 hourhiking trip in the rural mountains. If the hiking takes a long time and goesdeep into the mountains, or you want to cook lunch in the mountains, you needmore equipment.There are many small backpacks that do not have a carryingsystem. This type of backpack has a suitable carrying weight limit, preferablyunder 8kg.

2.Itinerary of 2-day tour: for the climbing trip over 2 days, the backpack mustbe reserved for camping (including bedding and tent) because you must spend thenight in the mountain. Generally speaking, if you can live in the mountainhouse overnight, you can choose a 45-liter backpack.If you need to carry yourown tent, it's best to use a backpack of about 55 to 60 liters.

3.Longitudinal walking activities on long mountain ranges: longitudinal walkingactivities in the mountains of Taiwan, because the days of activities in themountains are long, generally about 5 to 7 days, in addition to campingequipment, also must carry the required days of food;Most people will opt for apack of 70 liters or more, but women can also consider a pack of 60 liters.Somemountain friends are familiar with lightweight, only need to use a backpack ofabout 50 liters.

4.Longer days of mountain activities: some people who are engaged in theinvestigation of the ecology of mountain forests need more food and equipmentbecause they have to spend a long time in the mountains. Backpacks of more than90 liters can be considered.

Inaddition, when engaging in different outdoor activities, it is also necessaryto take different characteristics of backpack design as the basis forselection.For climbers who like to be engaged in exploration or jungle crossingactivities, the wear resistance of the backpack is the key to choose, otherwisein the jungle crossing or special terrain, the backpack will be very easy to bebroken or worn branches.For more specific technical mountaineering activities,the selection should also be made according to the characteristics of theactivity. For example, backpacks for stream walking should pay specialattention to water resistance. For backpacks for snow climbing, it should alsobe noted whether there is a relevant strap system for the use of ice axes,crampons, helmets and climbing ropes.
