Choosing the right dry bag size depends on how much gear you need to carry. Here’s a quick comparison:

A 30L dry bag is ideal for longer trips, as it provides enough room for extra supplies without being overly bulky.
How to Choose the Right Dry Bag Size?
To determine the best dry bag for your needs, ask yourself:
📦 What do you need to pack?
- For small essentials (phone, wallet, keys) → 10L dry bag
- For clothes and food for a weekend trip → 20L dry bag
- For longer trips, camping gear, and extra supplies → 30L dry bag
⏳ How long is your trip?
