Hardcore Waterproof Bag and Optimal Luggage Carry On!!

"I like this bag and bought it mainly because it fulfilled my requirements of being waterproof AND provides the optimal way of carrying as much volume as possible onto a long haul flight within stipulated airline carry-on dimensions (i. e. as a single unsegregated volume). There are a couple of things I would improve about the bag if I could. . but this applies to hiking functionality, which I have tested a few times. First is that one of the buckles on the left hand side of the bag sits directly in the opening to the bottle holder/netted pocket, which has a tighter elasticated opening. This makes it difficult/clumsy to get a bottle in and out of this pocket. . but is maybe finer for other smaller items. Secondly. . and mainly because I have a very large chest, the chest strap does not extend to connect across my chest, so a longer extension on the strap would be good, but this is more of a comment directed to the bag designers than a deal breaker for buyers. Only other thing I would change is to add a smaller additional outside waterproof zip pocket somewhere else on the bag for credit card sized items for easy access, in addition to the existing and convenient 'throw it all in here' single large zip pocket. Overall though, the bag does precisely the things I bought it for, the build quality seems excellent, I am very happy with it and would absolutely recommend to others looking for a waterproof bag you could literally swim with!! :)"

10/10 bag and 1000/10 customer service

"My bag came damaged right before christmas but no questions asked customer support sent me a replacement before I even shipped out the return! Oh, and did I mention my dad loved his gift?? I will only be buying my dry bags from COR surf! Thank you."

Kaili E. (5/5)

Nice bag

"I have had this bag for about 2 years. The 40 litre is perfect for me. I'm a scuba instructor so it gets a lot of use and is holding up well. Unlike other dry bags I've owned that begin to fall apart after heavy use. Just bought my husband one for a hiking trip."

Amanda P. (5/5)

Great for paddling and flying.

"This bag has been outstanding for carrying my wildlife camera rig both in the kayak and as a carry-on when travelling on expedition. Rugged and durable and the harness is the most comfortable I've seen in a dry-backpack. The pack has a rectangular profile, which allows me to fit an X-Large F-stop camera storage insert into it when flying, and the bag perfectly fits the carry-on sizers at the airport. Most dry-packs have an oval profile, which wastes a lot of space. This is my go-to bag when hiking, paddling or travelling with my camera rig. Highly recommended."

Excellent bag

"From a few weeks of use, the backpack is an excellent bag for protecting items. I use it for bike commuting, and I carry my laptop and other items I want to keep dry. The construction is durable, and the bag effectively protects its contents. The side pockets are great for bottles or loose items, the laptop pouch is spacious for a laptop and papers, and the pack is comfortable."
