Step1 clear your type of travel
This is a very critical step, including:
a Travel distance
b Season of travel
c The terrain and weather conditions of the destination
d Activities to be attended during travel
Step2 determines the basic type of backpack
Soft Packs/Day Packs:
The size of these backpacks is basically medium and small, and they don't have any brackets inside or outside. They don't have a good carrying system, just like the kind of backs you do when shopping.
a cheaper than large backpacks and easy to use
b Lighter and smaller
a For long distances, the capacity is too small
b The simpler carrying system can't bear the heavy load and it's not comfortable to carry back
External Frame Backpacks:
This kind of backpack has a very strong external support, which plays a good supporting role between the backpack and your shoulders and hips. More evenly distributes weight between your shoulders and hips, making your life more comfortable. The backpack and carrying system (adjustable shoulder straps, belts, chest straps, etc.) are fixed on the frame of the backpack.
advantage:
a More comfortable walking on a smooth or difficult road
b The internal capacity of the backpack is large, and most luggage can be placed in the bag. And there are intervals and side packages, making the storage of items more convenient
c There is more space between the body and the backpack than inside the backpack. This allows better air convection between the body and the backpack, keeping it cooler and more comfortable.
d It is cheaper than the same amount of inner bracket backpack
Disadvantages:
a Larger, heavier and bulkier than the same size of the internal support backpack
b When the bag is fully loaded, the backpack has a higher center of gravity and is more dangerous in poor road conditions. Especially on the way to climb or skiing
Internal Frame Backpacks:
This kind of backpack will move the bracket inside the backpack, making the bracket and backpack more closely integrated. It is also better to distribute the weight between your shoulders and your hips.
advantage:
a The backpack is more comfortable and close to the body, making the center of gravity more stable
b More flexible and easier to balance than carrying backpacks
c More advanced exterior design makes activities more comfortable, especially when crossing narrow spaces
d Very comfortable carrying, especially backpacks with adjustable carrying system
Disadvantages:
a. There are only 1- or 2 compartments in most backpacks, and there are few side pockets, which makes the sorting of the articles more troublesome (but now many backpacks can add outer packs)
b Since the storage space is narrow, it is more careful to put things. However, as long as careful and reasonable use, backpack life will be very long, and the older the more comfortable.
c Because the backpack is tightly integrated with the body, it is relatively hot and the air is not easily circulated. However, many manufacturers are now using a lot of high-tech synthetic materials on the piggyback system, which makes this problem better solved.
d The cost of the backpack will be higher than that of the outer stent. At present, the materials used for the backpack's brackets are often aluminum alloys, and some high-end backpacks even use titanium alloys as raw materials. Of course, their prices are also considerable. The shape of the stent is mostly long, but some higher-grade backpacks use a tubular design.
Climbing Pack with Side Package:
One is a large backpack with a volume of between 50--80 liters; the other is a small backpack with a volume of between 20-35 liters, also called an "assault pack."
The large mountaineering bag is mainly used for transporting mountaineering materials in mountaineering, and the small mountaineering bag is generally used for high-altitude climbing or assaulting the peak.
The mountaineering backpack is designed to deal with extreme environments. It is elegantly made and unique. It is generally thin and long. The back of the bag is designed according to the natural curve of the human body, so that the bag body is close to the person's back to reduce the pressure on the shoulder strap to the shoulders. These bags are waterproofed and will not leak even in heavy rain. In addition, mountaineering bags are used in mountaineering and are widely used in other adventure sports (such as rafting, crossing the desert, etc.) and long-distance travel.
Step3 determines the capacity of the backpack
The ideal choice is of course to have a backpack that can hold up all your equipment and you can carry it (of course, not only to back, but to be able to carry back for several days). Do not choose too big a backpack, although it can hold more things.
Volume: The volume of a backpack is often measured in "l" (L) units. Depending on the application, the volume can range from 30 liters (day-use) to 80 liters (long-range expedition). Most backpackers will use a backpack with a capacity of 50-60 liters because it is sufficient for general travel adventures.
Some factors that need attention:
a sleeping bag is usually placed inside the backpack, it often requires about 15 liters of space. When using the outer stand backpack, the sleeping bag can be bundled outside the backpack, but waterproof work should be done.
b Standards for backpack volumes marked by different manufacturers also tend to differ. The same 50 litre mark, there are some differences in the size of the packages produced by different manufacturers;
c Because the backpacker's personal conditions are different (such as height, physical strength and other factors), it will also affect the type of backpack you want to choose. Therefore, when choosing a backpack, it is best to ask experts in related fields (such as the salesperson of an outdoor shop).
Step4 About the design of the backpack
Once you have decided on the type and volume of your backpack, the next step is to compare the different design and unique features of the different backpacks.
The following elements can be considered:
Ease of use: Of course you need an easy-to-use backpack. Loading, taking and opening and closing should be very simple. And these often depend on:
a The number of intervals in the body of the backpack
b Interval design - split before and after, split up or down, or a combination of both
c The number and location of pockets
Functionality: At present, backpacks made by many manufacturers have volume adjustment function, so that you can better use your backpack. Perhaps a 50 litre backpack can be adjusted to achieve a volume of 60 liters. Most backpacks of this type have 50L+ or 50L+10 on the label. This design should include: longer straps (smaller items that can be tightened within the bag); expandable enclosures (to cope with increased equipment on the way); plug-in points (more equipment can be placed outside the pack) ; Free detachable packet (daily bag).
Durability: Everyone wants a package that can be used for a lifetime, unless it is outdated and does not want to use her. Then, the durability of the backpack is another important factor that you should consider. Try to pay attention to whether the backpack's materials are made of durable materials, in particular, whether the stitches on the zipper side are firm and whether the reinforced straps, strap buckles, and bag bottoms are available. In this regard, it is best to use brand-name products.
Suture strength: Including the belt strap and the body of the suture, the cover and the body of the suture, the ring and the body of the suture, the suture between the fabric, the tape and the body of the suture and so on. (The sutures in the key areas are generally multi-channel, multiple insurance).
Accessories quality: Accessories include waist buckles, all pull training, shoulder strap and chest strap fasteners, cover and body fasteners, and external fasteners. (Fasteners are components that are used repeatedly and are resistant to fatigue, are not brittle at low temperatures, and are strong and reliable).
Fabric selection: Including abrasion resistance, waterproof technology, fabric weight, anti-tearing, softness, and UV protection. (Tear-proof fabrics are mostly mesh-shaped; general backpacks do not have a waterproof function and need rain cover; wear-resistant materials are mostly used at the bottom of the backpack, where the ground and rocks are most exposed). The HD number of fabrics used in backpacks is also an important index to measure the quality of backpacks. The number of HD shows the tightness of this kind of fabric weaving. Generally, the fabrics used in backpacks are mostly around 300--400HD, while the higher-grade fabrics use fabrics of 500HD or even 1000HD. At present, higher-grade backpacks will use DuPont's CORDURA fabric, which is a high-strength tear-proof product. Many manufacturers will use CORDURA to make the bottom, and it is more useful to make CORDURA for the entire backpack (such as several of BIG PACK's PERFORMIC series).
Waterproofness: Traveling will inevitably come into contact with rain or other people watering your bag, then a good backpack should certainly have strong waterproof performance. Although you can put a rain jacket on the bag or wear a raincoat that is large enough to cover your backpack, it is inevitable that your bag will still encounter wet backpack problems. Water resistance is not only related to the number of HD fabrics (the higher the HD number, the better the waterproofness), and more importantly, the waterproof coating inside the fabric. Nowadays, there are two kinds of PV and PU paints that are popular in the market. The performance of PU is better than that of PV. Of course, it will be more expensive, but it will be much better than pouring a pack of water.
Step5 Make sure she's right for you
Carrying comfort is the most important factor in choosing a backpack.
When picking, it is best to carry a full package, rather than just look at an empty bag. Keep the back of the backpack as close to your back as possible, and the backpack will become part of your body. Take a few steps to see if it's comfortable. Try several different backpacks and learn how to adjust the straps and belts from the salesperson to pick the one that is most comfortable for you.
It should be noted:
a Belt - the most important part of the piggyback system. It can carry most of the weight to your hips (to be precise, it should be the pelvis), reducing the burden on your shoulders and making you feel more comfortable;
b Strap - another important part of the piggyback system. A high-quality shoulder strap can be soft, comfortable and easy to adjust;
c Carrying the trip - not the journey of your backpack, this is the distance from the upper part of the strap to the upper part of the belt. This should be an itinerary that can be adjusted according to individual height conditions. Many backpackers have patented products in this area, such as the TGB (TUBULAR CARRYING SYSTEM) of BIG PACK.
Also note that:
a Whether the bottom of the backpack is double-layered, it can increase the durability of the backpack. The extension bag at the top of the backpack must be able to extend upwards, while the extension bag must be able to seal. The tight belt on the outside of the backpack must be able to tighten the backpack's volume and prevent it from shaking. Backpack side pockets must be easily removable.
b Backpacks are best equipped with traction rings and ice axes, and can carry crampons, snow shoes, and other items.
c The degree of waterproof treatment of the backpack and whether the zipper failure can continue to be used. The backpack must be waterproof. Although the backpack is waterproof, rain will still seep through the seams, the top of the pocket, or the zipper seam.
After checking the appearance, lift the backpack back to the mirror and note the following: The backpack skeleton must be 2 to 4 inches above the shoulder, and the upper bag must not exceed 5 or 6 inches on the shoulder, otherwise a backpack will be reselected. When carrying the belt, the center point of the belt must be in the middle of the ischium, and the end of the waist gasket should not be too close to each other, and the part with no gasket can not rub the stomach. Do not choose a belt that is too tight. Adjust the strap fixing point. The curve of the shoulder strap should be close to the back of the bearer. The shoulder strap should be about 2-3 inches lower than the top of the shoulder. Hold the shoulder strap with both hands and the fist should be lower than the armpit. The head cannot hit the top cover of the backpack and cannot obstruct the helmet. The chest strap must help the bearer overcome difficult terrain.
