Tips for choosing a backpack

According to the number of people
When traveling alone, you can choose a backpack of about 25~35 liters. When traveling with family members and children on holidays, from the perspective of taking care of your family, you need to choose a backpack of about 40 liters, and there should be more external systems to help your family carry umbrellas, cameras, food and other items.

According to gender
Due to the different body sizes and load-bearing capacities of men and women, the choice of outdoor backpacks is also different. Generally, for a short outing of one or two days, a backpack of about 30 liters for men and women is enough. For long-distance travel or camping for more than 2 to 3 days, when choosing a backpack of 45 to 70 liters or even larger, men generally choose backpacks of about 55 liters, and women choose 45 liters of backpacks.

According to the itinerary
For one-day round-trip outings, cycling, and mountaineering, choose a backpack under 30 liters. Two to three days of camping can choose 30-40 liters of multi-functional backpacks, more than four days of hiking, to place tents, sleeping bags, moisture-proof mats and other outdoor equipment, you can choose more than 45 liters of backpacks. In addition, the backpacks used for general outdoor activities and climbing mountains are different, and the backpacks used for mountaineering do not have many parts, so friends who like mountaineering should pay attention.

According to length
Before choosing a backpack, you first need to measure your back upper body length, that is, the distance from the cervical protrusion to the last lumbar vertebrae. If the length of the torso is less than 45 cm, a small bag should be bought. If the length of the torso is between 45-52 cm, you should choose a medium bag. If your torso length is more than 52 cm, you should pick a large bag.
