Review on KastKing Cyclone Seal Waterproof Dry Bags - Ultimate Storage Solution, 5L/ 10L/ 20L/ 30L Roll Top Sack, Military Grade Construction for Swimming, Kayaking, Boating, Hiking, Camping, Fishing, Biking, Skiing by Mark Harris

I use the small 5L size instead of the dry box for small items that I keep in the locker on my boat. I like a bag over a box because it's flexible and compressible, which gives me the ability to cram more stuff into the space. The orange color makes it easy to find in a dark compartment and has been very durable and dry so far. If I had one comment it would be very small - the material is quite stiff so it took some manual handling to roll the top properly, but I don't open and close it often and expect it to break over time becomes.
