What size backpack is suitable for a twenty-day business trip in winter?

Based on the 20 days of your business trip, winter travel usually requires you to carry more clothes and items, so you need to choose a backpack of appropriate size to accommodate your items. Here are some suggestions:

1. Consider capacity: Choosing a backpack with a larger capacity will ensure you have enough space to carry all your clothes and belongings. Generally speaking, a backpack with a capacity of 40 liters to 50 liters is more suitable.

2. Consider organization: Choosing a backpack with multiple compartments and pockets can help you organize your luggage better. This way you can easily sort and find the items you need.

3. Consider comfort: The quality and comfort of the backpack are also important. Choosing a backpack with good back padding and shoulder straps can reduce the burden on your shoulders and provide better support and stability.

4. Consider material and waterproofing: During winter travel, the weather may be wet or rainy, so choosing a backpack made of waterproof material is a good choice.

In short, according to the above suggestions, choosing a backpack with moderate capacity, good organization, high comfort and waterproof function can better meet your needs during winter business trips.
