Backpack inventory (Part 1)
The backpacks on the market are mainly the following brands: BIGBACK, VAUDE, SEATOSUMMIT, JACKWOLFSKIN, FOXMOOR, FREETIME, NIKKO, OZRKA, onepolar, INWAY. The prices and their respective characteristics of these packages can be found on the Internet, so I don’t need to be wordy, just talking about my personal experience.
Material of the backpack: The main bag fabric and straps of the backpack are represented by “XXX”D. “XXX” refers to the density of the nylon thread of the fabric. Generally, the main package is in 400D–1000D (mainly for the bottom of the package). However, there is also a DuPont ripstop material: Cordula, which is distributed in a grid on the surface of the fabric, which can effectively prevent the wound from being further enlarged after the fabric is cut. At present, BIGBACK, VAUDE, OZRKA and other backpacks all use this fabric, and there is a special sign “Cordula” on the bag body. If the bag body uses Corula, then the requirements for “XXX” D can be lower. 400D–700D is enough. Therefore, relatively speaking, the backpacks of BIGPACK and VAUDE are all around 500D-750D…… backpacks generally do not need to be washed, which is taken into account by DuPont when developing the backpack materials. If it gets dirty, just wipe it with a damp cloth or use a duster.
Waterproof performance: Although ordinary bags boast a waterproof degree of “1000”mm, that is an ideal static figure. In actual conditions, water slowly penetrates into the backpack, so be sure to prepare A rain cover……The rain cover should be bought a little bigger than the backpack, because in most cases there is an external tent or moisture-proof pad……It is best to keep the rain cover on the backpack when you go out, not necessarily Waiting until it rains can also prevent your backpack from hanging on or getting dirty……In fact, the air conditioner cover can also replace the waterproof cover, and it is much cheaper. In addition, the backpacks sold now actually have their own rain cover, but the merchants have separated them and sold them for more money……
The carrying system: This is the key to choosing a bag, and it is also Competitive weapons from major manufacturers, such as BIGPACK’s TCS carrying system, CR system, VAUDE and SEATOSUMMIT’s X carrying system, etc.……In terms of personal use, the TCS carrying system is the most reliable, strong, does not sway from side to side, and also Allows the weight of the bag to be distributed evenly under the waist. The X-carrying system is more comfortable and is more suitable for Asian body shape, and the shoulder width can be adjusted according to individual needs……CR system performs well in small capacity bags……Since BIGPACK launched the top-level TCS system, many Imitation, such as an OZRKA, also has side struts, but BIG uses titanium alloy, while OZRKA uses plastic tubes. There are many people who blindly admire the TCS system. In fact, the TCS system is completely overkill if it is not a long way to carry heavy objects.……
The correct adjustment of the carrying system is also a problem, because the current backpack There is almost no instruction manual about the adjustment system……If you buy a good bag, but you do not adjust the carrying system, then it is completely a decoration……So when buying a backpack, it is best to ask the seller about the adjustment of the backpack Methods

Backpack fasteners: the current backpack fasteners are basically “Duraflex”““ ;niffko” two. Most backpacks use “Duraflex”, only NIKKO’s backpacks use “niffko”. Relatively speaking, “Duraflex” is more professional in design and more durable than “niffko”. The material of the fasteners of the backpack is different from the general one, and it is made of resin instead of ordinary plastic. Because the resin will not be brittle at high and cold temperatures, and will not be broken by excessive bending deformation……Some people may think of titanium and aluminum alloys as fasteners——Ha ha, at extremely low temperatures, the metal surface will be passivated, and the skin will be passivated. The passivation layer sticks as soon as it touches it, like an ice cube, but the resin doesn’t.
In the process of placing and transporting the backpack, be sure to insert the fasteners to avoid being hung up by other hard objects. It is worth noting that there are two series of “UTX” and “WooJin” in “Duraflex”. “hellip;”hellip; “UTX” is the mainstream, strong and tough, and most of them are buckles of this series. pieces. But the best is “WooJin”, which has the best toughness among the fasteners I have used. The inserts of its male fasteners can be bent more than 90 degrees without breaking. SEATOSUMMIT’s backpacks are specified to use all the fasteners of this series. NIFFKO can also be regarded as a brand fastener, which is characterized by a very tight card line, mainly used in some civilian brands of sports bags, such as JACKSPORT…… , Some are plug-in straps, some are plug-in buckles (you need to buy additional plug-in straps) …… Strangely, the plug-in points of well-known brands such as BIGPACK and VAUDE are much less than those of SEATOSUMMIT and INWAY. Although the plug-in can increase the capacity of the bag, it is also easy to cause uneven loading of the backpack and inconvenience in movement. It is like a person who is used to driving Otto to drive a long Dongfeng truck. The backpack is not recommended to be attached to the outside, except for the water bottle cover…… it is best to bring a cover for the external things, otherwise it will be easy to wear. External accessories must be bundled firmly, and it is recommended to use optional external straps for reinforcement, especially for heavier tents……
Backpack Big Inventory (Part 2)
Backpack brand and choice: When buying a backpack, you must first consider your height and carrying capacity. The purpose of the backpacker trip is very important. You must choose at least 50 liters for mountain climbing, and you need to use a small bag of about 20 liters for caving (there are professional caving bags). If you buy a 65 liter bag to accompany PLMM shopping, you will be met with BT… ;Practicality is the most important, simplicity is beauty……
Comments on mountainsmith and bigpack backpacks
hereinafter referred to as M and B
carrying system: this is a backpacker friend the focus of most concern. Compared with the APS system of M and the TCS of B (the CR and AIRFLEX systems are not in the same grade, so they are excluded.), M and B both emphasize that the backpack should focus on the waist of the person, that is, the natural bulge of the coccyx of the person. That part, this will reduce the pressure on the shoulders of the backpack (in fact, all backpacks are designed to be carried). B’s TCS relies on two aluminum alloy (titanium alloy) tubes. When carrying heavy objects, it is equivalent to carrying a TCS tube frame instead of the body, so B can concentrate the body’s load-bearing point on the tail in this regard. , 4 directions of the back blade, and it is also very good to prevent the shaking of the bag body, especially in the dangerous area, when the human body itself needs to swing a lot, TCS can reduce the inertial impact of the shaking of the backpack.
M’s APS system emphasizes the closeness of the bag body and the back of the human body. Although the adjustment of the APS carrying system is much more complicated than that of the TCS, if it is adjusted properly, the entire bag body can be very humanized and close to the body. On the back of a person, the comfort is much better than that of TCS with 4 obvious stress points. Of course, APS also focuses on bearing capacity on the waist and tail. A thick fiber foam version is used to close the person’s back, and then two lengthened aluminum alloy versions of the CR carrying system similar to B are used to transfer the pressure of the bag body on the shoulders and back to the waist. The anti-slip function of M is realized by two small aluminum alloy tubes on the left and right of the bottom of the backpack, which also has a taste of TCS, but the actual effect is the same as the anti-shake design of JACKWOLFSKIN and VAUDE, which has the same effect. It is not as good as TCS, and the left and right backpack straps connected to the waist pad must be tightened to make the anti-sway and side-slip function work (this involves the material of the backpack straps to be introduced later).
In addition, M’s shoulder straps have a big feature: because the M’s carrying system is more effective than TCS to put more pressure on the waist and tail, its shoulder straps are slightly more than the B bag. Thinner and narrower, it is very suitable for the narrower shoulder width of Asian race. It will not be like B. The two fat shoulder straps increase the shoulder pressure area and disperse the shoulder bearing force, but will reduce the shoulder width. The narrower shoulders are painfully pinched. And with the same weight of the bag, the shoulder force of M is much less than that of B, and the main pressure is transmitted to the waist and tail by the APS system.
Remind again that M’s carrying system is complicated to adjust, and it is best to let the merchant explain clearly when B buys it.
Backpack material design: Obviously, B’s backpack straps are much denser and stronger than M’s. The straps of the M bag are too soft and slide easily. When the backpack is heavy, the straps have to be tightened frequently, but they come loose after a while. This is the fatal flaw of the domestically produced M package. However, the waterproof effect of the M bag is much higher than that of the B, and the M is most famous in the world for its J-shaped large-ring buckle zipper, which allows the contents of the backpack to be easily taken out regardless of the upper and lower layers. It is a very user-friendly design, and it is also a selling point for M to survive in the backpack industry. The top bag of the M bag can be detached separately to make a simple waist bag, or it can be combined with the waist pad to make a stronger waist bag. This design has been used by FREETIME and JACKWOLFSKIN, but when the top bag is usually too heavy, the back When leaning forward, it is easy to touch or press the back of the person’s head, which is very uncomfortable. And B uses a conical top bag, which is not removable, but no matter how many things are installed, it will not press the back of the person’s head. There are two large storage bags on the left and right sides of the M bag, which are more atmospheric than the B bag, and can hold a lot of things that are often taken in and out. In terms of fasteners, M can be said to be the culmination of various companies. The main fasteners use DURAFLEX, which is very durable, which is the same as B; all zippers use YKK, while B uses YBS, which is not as strong as YKK, and For the fasteners used for the adjustment of the carrying system, M uses NIFFCO. I have introduced this kind of fasteners before, which can clamp the carrying straps very tightly. Although the elastic latitude is not as good as that of DURAFLEX, for the carrying system that does not need to be adjusted frequently, It can be tightened more tightly than the DURAFLEX, which makes up for the defect of the M strap being too soft.
Backpack capacity: B is much worse than M. M55 liters of FOSTFIRE can hold about 100 liters of things when pulled up, while B’s maximum TCS is 80 liters, which can only be equivalent to Ordinary backpacks have a capacity of about 60 or even lower. In terms of plug-ins, the two are very economical, not as good as those of SEATOSUMMIT. But M has more plug-in points than B, which can be supplemented by purchasing plug-in belt

Backpack nobles ——UK karrimor vs. Italy Ferrino
karrimor and ferrino are the two backpacks I carried between 2001 and 2002, and have been to Medog and Nepal. It was later sold. This is a review I wrote after I sold these two bags. Hereinafter referred to as K and F, respectively.
Backpacking system: There are many kinds of carrying systems for F, including BEA (the aluminum alloy plate at the back of the backpack can be extracted to facilitate the randomness of loading supplies. For example, a 40-liter bag does not carry a lot, just The height and width of the backpack can be tightened after removing the aluminum alloy back plate, which will not make people feel that the backpack space is too wasteful). There is also an EBP system, which uses a similar back pad that can be lifted up and down. More advanced is a back pad made of a fiber material produced by DuPont. I have tried it, and I feel that it is not as stiff as the general aluminum alloy back system. It is softer and has good elasticity. When bending over, there is no very back feeling of the aluminum alloy plate. The restoring force far exceeds that of the aluminum alloy plate, because the aluminum alloy plate of many backpacks will be deformed and bent after carrying heavy objects for a long time, which will seriously affect the comfort of the back. Then there are some other common backpack designs, which feel similar to BIGPACK’s CR and MOUNTAINSMITH’s APS.
K is a very special SA intelligent adjustable carrying system, which is the most creative design in the carrying system I have seen. Its carrying system as a whole continues the aluminum alloy and can be adjusted up and down, but the most important thing is that its adjustment method is to adjust according to the weight of the backpack after the backpack is worn. Instead of the general backpack, you have to adjust it and then carry it back. If it is uncomfortable to carry, you have to put the backpack down and then adjust it. SA has a revolutionary design, leaving a pull-up strap on the left and right at the bottom of the back pad. The top of the shoulder pads of the backpack is marked with a blue color bar. After carrying the backpack, no matter how heavy the backpack is, the first thing to do is to adjust the blue strips on the shoulder pads to be pressed against the flattest part of the shoulders, that is, to take care of the stress on the shoulders first. Then pull down the pull-up belt at the bottom of the back pad and pull it down until it is tight. In this way, the load-bearing point of the backpack can be automatically transferred to the middle and upper part of the lumbar spine, which is the best load-bearing point of the back of the human body. If it is another bag, you must first pull out the carrying adjustment belt under the rear pad, adjust it by feeling, and then carry it on your back. If it doesn’t feel right, I have to put down the backpack again and adjust it again. Moreover, such adjustments are all out of thin air, and it is impossible to reasonably distribute the force of the carrying system according to the weight of the backpack, especially for inexperienced beginners. The entire adjustment system of SA is adjusted according to the characteristics of the body shape after the heavy object is placed on the back of the body. It can be completed by one person without assistance. This is probably the most distinctive selling point of the K package. In contrast, F’s burden is not as fresh as K’s.
Backpack material: top backpack, top price, naturally in addition to cordura wear-resistant and tear-resistant material. Kelvar breathable fiber cloth is also used. This material is mainly distributed in the back pad where the backpack is in close contact with the human body and is easy to rub and sweat. Equivalent to quick-drying fabrics, the purpose is to quickly dissipate the body’s heat and keep the body dry. After I tried it, I felt that the fabric was still very “cool”. After exposure to the sun, the temperature of Kelvar was significantly lower than that of cordura, and it still felt cold when placed indoors. Especially the back, after a long hike, the back sweat is less than the general BIGPACK and JACKWOLFSKIN.
In addition, F has a backpack, the bottom of the bag is not the ordinary 1000D CORDURA, but the synthesis of VIBRAM Rubber fiber fabric. Italy’s VIBRAM sole is very famous. This bag sole is also famous. It feels like a lot of rubber balls are distributed on a piece of fiber cloth. CORDURA speaks the same language.
K uses SUPERMAX, a material similar to COOLMAX, and the breathable design on the bag is COOLMASH, which is excellent in perspiration and heat dissipation. On the webbing of the backpack, the overall belt of K is tighter than that of F, especially for the small details, the density of the webbing of K is higher. Moreover, the K webbing is also divided into colors according to different purposes, such as the yellow one is the pull-up adjustment belt, and the gray one is the edging pressure belt…… When packing the backpack, you can easily find the required backpack belt by color. As for other backpacks, they are all black and crowded together, often making the fasteners find the wrong object. Backpack’s fasteners and zippers: F uses DURAFLEX’s lobster buckle, which is tighter and more secure. Better than WJ series fasteners. And this kind of fastener is designed to be very thick, I believe that the foot should not break.
K does not continue to use the traditional DURAFLEX, although 70% of high-end backpacks use it. K’s fastener is an arch bridge buckle designed by itself, like a key inserted into the lock hole. Relatively speaking, the surface compression resistance of the arch is the strongest, such as the arch bridge. Therefore, although the thickness of a single panel of K’s arch bridge socket is not as good as that of DURAFLEX, the hardness index of compression and crack resistance is higher than that of DURAFLEX.
I personally feel that K’s arch bridge buckle is a sign of rivalry with other backpacks. It is naturally more reliable than DURAFLEX in terms of withstanding the splitting force and pressure from various aspects, but DURAFLEX’s fasteners It is flat and naturally has its own advantages in sticking to the backpack body and preventing the webbing from sliding left and right. And now DURAFLEX is basically eliminating the WJ series and the STEAL series with lobster buckles. It may also want to challenge the arch buckle in terms of compression resistance.
It is worth noting that F’s high-end bags all use waterproof zippers, that is, the seams around the zipper are coated with a rubber film to resist the penetration of water. As for the K bag, I have only seen a 35-liter model with a waterproof zipper in the middle. Although the waterproof zipper is not a new technology, it may not be noticed by everyone. Because before this, the waterproof zipper of the backpack was solved by the method of fiber hemming and sewing. But the effect is very unsatisfactory, can not withstand the heavy rain.
As for the three-end crimping sewing on the backpack, the reflective zipper, the bag-shaped design ……K and F have taken it out as a selling point. But I personally think that everyone’s backpacking habits and travel needs are different, so I won’t comment on these different opinions.
