I’ve had mine all spring and summer. It’s past the float test many times in my boat. In fact it sits in water most of the time it’s in the boat and it has never let in one drop of moisture ever. It hasn’t been exposed to torrential rains because we didn’t have any this year but I have no doubt it wouldn’t have leaked at all because of the zipper design. I added a piece of foam I got from a pilates matt to the bottom with some spray adhesive to prevent wearing the bottom out sliding it on the boat floor. It holds a TON of gear and I’m considering another one for my expanded camera gear (that’s how much I trust it). I keep lines, reels, light, lighters, extra clothing, and fly boxes in mine.
Big thumbs up here for the Simms large boat bag!
