Great pack and great seller!
Updated review - I love this pack for camera equipment on canoe and kayak trips - the wide zippered opening makes it easy to get gear in and out, much better than narrow roll-top dry bags. The waterproofing has withstood several rain storms, constant dripping from paddles and six-day stretches of sitting in puddles in the bottom of canoes and kayaks, and not a drop of moisture has made it inside. The original pack I received had an issue with stitching on the straps but I reached out to the company and they were amazingly responsive! So very happy with this pack and this company. Recommend it highly.

Fantastic waterproof bag. Pricey BUT worth it!
If you want a spectacular waterproof backpack that works like a charm, looks nice and handles well, this is it for you. The included silicon lubricant really helps on the zipper for the movement to seal things easier but I never had issues. This is easy to fold down and put away in a piece of luggage as it's not huge but it is big enough to hold plenty of what is needed. I have only used this on a couple trips so far and there has been no quality issues at all with it and I expect it to hold up for a long time. Big money but quality merchandise. This is what you need when you go hiking or on some kind of water related adventure. Even going on boat excursions and snorkeling. This can serve as a great flotation device.

Good product.
Perfect for inflatable kayak trips. I use as a dry bag and use leash to kayak. Much easier dry bag when hiking in a little with kayak. Used it several times. It gotten wet but never submerged for long periods. But while sitting in inflatable kayak it does get wet and everything inside I dry when I unzip. Works just like a backpack but it can keep your stuff dry unlike a regular backpack. Works as advertised used it all summer while fishing. Fits a couple of Plano boxes in it as well as light jacket, long sleeve shirt and hiking “tennis” style shoes size 12 men’s thick pair socks. All I needed but had a little more room. Seems and zippers have held up and not rusted. Seems to be a quality product to me. I hope to get another year out of it.

Love the bag but needs more pockets.
I just received my backpack, I got the biggest they made, seems to be very well put together for waterproof. I love the air valve, you can blow air into it for extra floatation or purge air out to make like a vacuum seal. The main zipper is a little stiff/tough, I assume that’s to keep it watertight. And you MUST close it 100% all the way to make sure the bag is watertight. However this makes it a bit more tough to reopen. One complaint I do have is, Not enough pockets. Because it’s waterproof I understand they want to limit the water intrusion, however more pockets could be made on the inside. (Main compartment). You have one smaller, but deep pocket in the front of the bag, drink holder pockets on the sides, and in the main compartment you have the main space and a computer sleeve type of space. When boaters are using this bag, we carry a lot of equipment we would like to keep readily available but still waterproof. So it would have been good to have more pockets. GPS, Satellite phone, valuables, batteries, other boating equipment etc. So for that reason I can’t give it a full five stars

durable and waterproof
Great product! Durable and waterproof and works for use when walking/hiking in the rain. Mine is primarily used in canoes and kays and has been great for that. Good zippers and handles.

A Well Made and Functional Waterproof Pack
This is a great product. It fits well on my back and is not too large. I love that it has straps that secure across the chest and the waist. It is very waterproof - the zippers form a tight seal. I used it on a trip to Patagonia and it easily held my cameras and cell phone, extra clothing, water, wallet, etc.
