How do I choose a dry bag?

How to choose a proper dry bag depends on the following aspects:

1. Purpose - Consider what you'll be using your dry bag for. Will it be for camping, kayaking, or boating?

2. Material - Different materials have different durability and waterproof ratings. Typical materials used are nylon, polyester, PVC, TPU, and silicone. PVC is the most affordable, but it also has the lowest waterproof rating. TPU and silicone are preferred for their high waterproof rating and durability.

3. Size - The size of the dry bag is important as well. You'll need to consider how much gear you'll be carrying, and choose the right bag size accordingly. If you're going on a multi-day trip, you'll need a bigger bag compared to a day trip.

4. Closure System - Consider the type of closure system for the dry bag. Some popular options are roll-top, zip-lock, and buckle. Roll-top closure is the most common and reliable for keeping water out.

5. Ventilation - For items that need proper ventilation, such as wet clothes or towels, choose a dry bag with a breathable mesh panel or vent.

In conclusion, the choice of which dry bag to buy depends on your purpose, the material used, size, closure system, and ventilation. Make sure to choose the one that best suits your needs.
