Traveling bags are also called travel packages, which are packages that are prepared for travel or travel. Travel bags can be divided into backpacks, handbags and trailers. In the selection, we should consider the volume and style, in addition to the user's figure and shape, as well as load capacity and other factors. Because the outdoor travel bag is used in the special environment, the material and craft of the traveling bag are put forward higher request. All the travel bags to the position of the force is sewn back needle sewing three times, so that the force position sturdiness and durability.
According to the different volume of travel bags, the general can be divided into large and medium-sized travel bags.
Large bag volume in 50 liters, suitable for long-distance travel and comparative professional exploration activities. For example, when you want to go to a region like Tibet for a long trip or a mountaineering expedition, you should certainly choose a large travel bag with a capacity of 50 liters or more. Some medium-and-short trips also require a large travel bag if you need to camp in the wild, because only it can fit the tent, sleeping bag and sleeping mat you need for camping. Large travelling bags can be divided into mountaineering bags and travel bags according to their different uses.
The mountaineering bag is usually elongated, so that through the narrow terrain, the package is divided into upper and lower layers, the middle is separated by a zipper interlayer, so it is very convenient to take the items. The side of the bag and the top can be outside the tent and cushion, virtually increase the volume of the bag. Bag outside also have ice set, can be used for bundling ice, snow cane. The most noteworthy is the back structure of these bags, with a lightweight aluminum alloy frame inside which supports the package, the shape of the back is designed according to ergonomic principles, the back bandwidth and thickness, the shape of the body with the physiological curve of the "S" type design, and also to prevent the straps to both sides of the chest belt, so that the bag is very comfortable. And these bags all have a strong, generous and comfortable belt, the height of the strap can be adjusted. Users can adjust the strap to fit their height according to their own figure. Generally speaking, the bottom of the bag is located above the hips, so that more than half of the weight of the bag can be transferred to the waist, thereby greatly reducing the burden of the shoulder, reducing the long-term load caused by shoulder damage.
Long-haul travel bag package structure and mountaineering bag is similar, only the package is lenient, and with many side bags, in order to classify the pieces of objects, the front face of the long-distance travel bag can usually open all, take items very convenient.
The volume of medium-sized bags is generally between $number liters, the use of these bags more extensive, 2-4 days of field travel, travel between cities and some far-reaching non camping self-help travel, medium-sized bags are no longer suitable. Carry clothes and some daily necessities can be fitted. The style and variety of the medium-sized traveling bag are more diverse. Some bags add some side pockets, which are more conducive to the distribution of goods. The back structure of these bags is roughly the same as the large travelling bags.
The volume of small bags in the 30 liters, these bags are generally used in the city, of course, for the 1-2-day outing is also very suitable.
Because the outdoor travel bag is used in the special environment, the material and craft of the traveling bag are put forward higher request. All the travel bags to the position of the force is sewn back needle sewing three times, so that the force position sturdiness and durability. The button and other parts of the travel bag can be made into antifreeze, tamper-resistant and 120 degrees Celsius deformation is not damaged. The outer material of the bag is mainly 420D Oxford nylon, 1000D nylon, 600D or 1000Dpolyester (polyester), or 1000D cordvra and other materials. 1000D material density is high, very wear-resistant, suitable for use in the field. Cordvra is a well-known high-grade wear-resistant nylon roving fabric developed by DuPont. The wear resistance of the material is much higher than the general nylon or polyester, and light weight. More than 90% of the world's famous brand of travel bags are used in this prestigious nylon material. These materials can withstand the pressure of 0.5m~2m to keep the inside of the package dry. Some materials also have a tear-proof function, once punctured, the gap will not be torn apart. Canvas material is also used for the manufacture of travel bags, and the Republic of canvas is a typical example. Because the canvas is more wear-resistant and the density of rain-proof effect, texture is also very soft, so very popular.
