The ability to keep water out and your gear dry is the most important job of a dry bag. To test each product's capacity in this metric we first exposed them to regular recreational use. We used them for paddle boarding, beach days, and river trips and took careful notes about the level of water exposure they received and how the internal contents fared. We then subjected them to more rigorous testing. Each product was filled with towels, closed according to the instructions, and held underwater for 30-seconds. The towels and inside of the bag were then evaluated for water. Last but not least we attached each bag filled with dry towels to a leash on the back of a paddle board and dragged them through a lake for 30-minutes. Afterward, we investigated the level of water in each product.
Ease of Use
We set out to determine how the product packs, how it carries, and how simple it was to retrieve contents during an activity. We used each model for a variety of adventures and packed everything from clothes to cameras to sleeping gear inside.
Certain models are best suited for specific objectives. In order to tease out the specialists, we thoroughly investigated and used the individual features of each product. We paid particular attention to the closure system and the lash points and made note of any unique characteristics like backpacking straps or pockets.
To best assess durability, we spent months subjecting these products to regular use and abuse. We judged each on the material of the main body and the features such as clips and straps. We also evaluated the closure-system and how well it stayed sealed during use.
