Purchased 23 of these bags for a Boy Scout canoe/kayak trip. No complaints about the waterproofness, but we had 2 buckles fall off right out of the package, due to bad sewing. Just the right size to stow in the cargo hatch of the kayaks. They were on sale, so they were a good deal for what I paid. We hope to use them again and again. Just be sure to pick it up by the grab handle and NOT the buckle.

This pack will keep your gear dry, despite mother nature's best efforts. I've taken this pack on several long trips into the BWCA and have put it through considerable abuse. It is holding up beautifully - all the seams are still 100% and there are no signs of the pack breaking down at all.
I had this pack loaded to the gills when my canoe got tipped by some huge waves in the middle of a large, remote lake. The bag was in the water for 20 minutes before we washed ashore, yet everything inside of it stayed 100% dry. It saved the trip.
The one complaint I do have is that the shoulder straps are not very comfortable on long portages.

I bought this bag to use on canoe trips this summer. Still a little cold out for those but I did get to use it on a roadtrip this past weekend. Didnt have room in the cab of the truck so I put most everything I had in this bag and placed it in the bed. Downpours all over the place! Yet, everything inside stayed 100% dry. Good material, well built dry bag (USA). Yeah the straps aren't the greatest, but then again, its a dry bag and does its job...well.
