Choose backpack according to the itiner
One-day round-trip excursions, cycling, and mountaineering activities, choose a backpack of 30 liters or less. Two to three days camping can choose 30-40 liter multi-purpose backpack, such as KingCamp outdoor backpack KB3291, light weight, multi-function, with sliding chest adjustment system, suspension air conditioning system, shoulder strap quick adjustment system, waist storage Things, convenient, practical, safe and comfortable.
For hiking on more than four days, you should place outdoor equipment such as tents, sleeping bags, and moisture-proof mats. You can choose a backpack with a height of 45 or more. In addition, the general field activities are different from the backpacks used to climb the mountains. The backpacks used in mountain climbing do not have many parts. Friends who like mountain climbing need to pay attention.
Choose backpacks based on number of people
When you are outing alone, you can choose a backpack of 25 to 35 liters. When traveling with family and children on holiday, from the perspective of caring for the family, you need to choose a backpack of about 40 liters. There are more plug-in systems to help your family bring umbrellas, cameras, food and other items.
Choose a backpack based on your length
Before choosing a backpack, you first need to measure your upper back length, which is the distance from the cervical vertebrae to the last lumbar vertebrae. If the torso is less than 45 cm in length, you should buy a small bag. If the trunk length is between 45 and 52 cm, you should choose a medium bag. If your torso is more than 52 cm in length, you should pick a large bag. The standard of reference is that the hips and legs should be visible from the back when carrying the backpack. If you only see one big backpack and two calves, it is wrong and dangerous.
Choose a backpack based on gender
Because of the different body and weight of men and women, the choice of outdoor backpacks is not the same. Usually a short day outing for a day or two, a backpack of about 30 liters for men and women will be fine. For long-distance travel or camping over 2 to 3 days, when choosing a backpack of 45 to 70 liters or more, generally men choose a backpack of 55 liters and women choose a backpack of 45 liters.
In addition, the style and comfort of the backpack should be chosen before you try it. Avoid lifting the frame or the top pocket when you look up. All the parts of the backpack that come into contact with the body must have enough cushions, the inner frame and the seam of the backpack. The line should be strong. Pay particular attention to the thickness and quality of the shoulder straps, as well as check for chest straps, belts, shoulder straps, etc., as well as their adjustment straps.
