I've had a couple of these for a couple of years now, and so far so good! I don't recall ever totally dunking them, but they've seen plenty of wet conditions (bottom of a canoe, strapped to a bicycle rack in the rain) and I've never had an issue with moisture inside. I'm not particularly careful with them, and they seem to be holding up just fine.

Worked very well on a -35°C snowshoe trip. Kept my clothes organized in my expedition duffel bag.

Very happy with my first use in -35°C on a snowshoe trip, packed very easily into my large backpack and kept my clothes dry and organized.

WE TRIED THESE DURING RIVERINE OPS IN COLOMBIA, SA - NO GO! GENERAL KNOWLEDGE.... NO MATTER WHAT NAME BRAND "WATERPROOF" GADGET YOU PURCHASE, YOU NEED TO TEST IT OUT USING A PIECE OF PAPERTOWEL/PAPER/ETC BEFORE EVEN THINKING OF PUTTING YOUR EXPENSIVE ELECTRONIC(S) INTO IT AND TAKING IT FOR A SWIM... WORKING IN THE SPECIAL OPERATIONS COMMUNITY FOR OVER 25 YEARS, I HAVE FOUND THAT NOT MANY "WATERPROOF" PRODUCTS ACTUALLY DO WHAT THEY SAY AND FOR US, IF OUR MISSION ESSENTIAL GEAR/ELECTRONICS GET WET, IT WILL BE A MISSION FAIL OR IT MIGHT EVEN BE A CASE OF LIFE & DEATH DUE TO GEAR LOSS. I TAKE MY WATER PROOFING SERIOUSLY BECAUSE OVERKILL NEVER FAILS.

This is my 4th or 5th durable stuff sack, actually my second durable dry bag. With the exception of the one I lost I still have the rest, they are in perfect condition after 10 years of abuse. I just have a growing family and needed more. Sadly OR discontinued the stuff sacks, but they still have the dry bags, get them while they still have them, they are bullet proof.

This is not a proper dry sack. I placed a digital SLR in it on a easy canoe trip. The boat was never capsized; a small amount of water hit the bag during the day. I opened the dry sack the camera was wet with water all over it. Do not buy this or any similar product designed like this. It is simply untrue to sat it is waterproof. A total failure that could have cost me a $2000 camera had any large amount of water hit the bag. A waste of my money. Let me be clear I have other dry sacks that work great. This doesn't - do not buy it.
