CHRIS H Very much so. i have used this bag both to keep my gear dry and i have used it as a cooler keeping beverages on ice. it is a good bag no doubt. (good heavy material)

Zack W Yes it is waterproof. Enjoy it! Zack.

SunnySports S Coghlan's actually didn't release a weight on this product. I can however tell you that shipping weight on this product is about 1/2 a pound. I hope that helps. Stay safe and have fun out there! Neal
