Is the 40L mountaineering bag used by girls big enough?

I suggest buying a better backpack, 45 liters. The reasons are as follows: 1 camping should bring its own equipment, sleeping bags, damp-proof mats, tent lights, catering tools, water and food, and change clothes (underwear and shirts). Don't look at other people's mountaineering bags, and hang a moisture-proof pad on the backpack. Actually, this is not good. All the equipment, including food and drinks, are properly packed in bags. A good backpack is not about appearance and practicality. The first requirement is whether the backpack system is comfortable. A good bag should be comfortable to carry and comfortable to shoulder and waist, so it is labor-saving and comfortable. Even if you buy a good bag, it will take half a day to achieve your body's coordination just by adjusting the various shoulder straps of the bag. Strong expansibility, suitable for 45-liter bags.

Personal suggestion 600-800 yuan's backpack, 200-300 tents look like hundreds of sleeping bags. You don't have to buy tableware such as a stove.

There are many outdoor stores in Beijing and other places with discounts. The advice I give you needs you to shop around. In fact, this price is not available.
