Cotton Carrier DryBag (Large 16")

I was skeptical about the roll-top closure, but after dunking it in a stream to test it, not a single drop got inside my camera body. The interior padding is thick enough that I don't worry about bumps when hiking in the rain.

Fits my DSLR with a 70-200mm lens attached, and the roll-top seal kept everything bone dry during a rainy hike. The clip system on the back is a nice touch for quick access.

Took this out in a proper downpour and my gear stayed bone dry inside the 16-inch bag. The roll-top seal is tight enough that I didn't worry once about the rain getting in, and it fits my camera body with a lens attached without feeling cramped.
