I first saw these bags at NWTF in Nashville a couple years ago. I wanted one so bad because I had recently went duck hunting with a "waterproof" backpack from another company that we won't name.... needless to say, my stuff got soaked and I had a bunch of wet shells that wouldn't fire and a ruined cell phone that didn't make calls.
This past season, I took the plunge again but this time with a Hella Dry bag and let me tell you! If I wasn't a believer before, I am now! My clumsy self tripped over my feet on a boat hunt and lucky for me, I was wearing my bag. Not only did everything stay dry (hella dry I must say) but I floated!! This bag saved my ass and my gear! Lifelong customer now fellas!
