How should you choose the capacity of a camping ice pack bag?

The key to choosing the capacity of a camping ice pack is to match the number of travelers, the amount of food, and the duration of use. Prioritize slightly larger packs over smaller ones.

Core Basis for Capacity Selection:

Based on the number of travelers: 1-2 people: 15-25L, just enough for 2-3 days of food and drinks; 3-4 people: 30-45L, to meet the needs of sharing food and chilling; 5 or more people: 45-60L recommended, or prepare two medium-sized packs for more flexibility.

Adjusting based on usage duration: For a short 1-day trip, reduce the capacity by about 10L; for 2 days or more, add 10-15L to accommodate the extra storage needs of perishable items.

Consider the type of items: If you need to bring a large amount of meat, beer, or other bulky/refrigerated items, increase the capacity by 10%; if you are only carrying a small amount of fruit and drinking water, choose the basic capacity.
