It's hard to find a drybag that is both durable and packable. Most durable dry-bags are a thick PVC material; those are great but don't pack down small. This 65L bag manages to be incredibly durable, and rolls up as small as my other 15L dry bags.Everything else about the bag is designed intelligently: great tie downs, oval shape, replaceable buckles. I've owned one for a few years and just bought a second. My first one is barely showing signs of use; I use it at least monthly on a SUP (fits an iSUP pump and carry bag really well, plus any extra clothes and snacks for the paddle)

I bought 6 of the 65 L Big River Dry Bags to hold all my gear for an extended wilderness river rafting trip in southern Utah. The bags were the perfect size and packed/stacked very well. There were no major rapids on the river and the bags were simply strapped down on the back of the raft. For such a long trip in a sandy environment, I think the Hydraulic Dry Bag would have been a better choice. Although they held up pretty well, moving camp each day and loading and unloading every morning and night sure took its toll on the bags. The temperature was also 100+ degrees and the loops on the side for strapping the bags down simply peeled off the bags. It looks like they were just held on with adhesive and the heat melted the adhesive and the loops became worthless. ... MoreI bought 6 of the 65 L Big River Dry Bags to hold all my gear for an extended wilderness river rafting trip in southern Utah.

4 Star Product 1 star for deceptive marketing specs. Purchased a 5L to keep my sleeping bag dry and water proof. Way to small. I would have expected the specs listed to be the usable space. The Listed size are of an open flat bag. USELESS INFORMATION! My fault for not doing more research. Sea to Summits fault for not providing more usable data. Beware! Your going to loose 5" on a 5L when you roll it closed. The bag will only be 10" long.

This is my second big river dry bag. Had to get a second and larger 30 liter size after being thoroughly tested with my smaller one! I have used the 4 liter size for a few years now and taken it all over the world and is in great condition even after much adventures and abuse. It provides ample protection for water activities and is a good light enough weight to keep in hold my daily items even when I won’t be near water.
I have the 20 L and 35 L bags. I used the 35 L bag on top of my rear bike rack for touring/bikepacking on backroads in Scotland. I used the 35 L bag as it still fit on top of the rack. The 20 L would have held my stuff - barely. Having the extra space in the 35 L made packing easier though. Any extra space could be cinched down easily. With the Hypalon side loops I could secure the bag really well to the rack. The roll top closure snapped around my seat post for further stability. The oval profile of the bag made for a degree of stability on the carrier as well. The cloth was light enough for biking and heavy enough to take abuse - spot on. So, what's Sea to Summit's opportunity? Well - more exterior loops would make attaching elastic webbing possible to stuff a ... MoreI have the 20 L and 35 L bags.

The cloth was light enough for biking and heavy enough to take abuse - spot on. So, what's Sea to Summit's opportunity? Well - more exterior loops would make attaching elastic webbing possible to stuff a jacket without going into packs. Some loops close to the roll top could make it easier to make a dedicated seat post attachment as well. A more squared off profile (rather than oval) with a flat bottom would make racking even better. I see enough of these bags on bikes already, that a dedicated bike model would work great. A volume less than 35 L and more than 20 L would work great (27.5 L I guess). No matter what you use this bag for, it's a superior outdoor product as is.
I originally bought some of the 13 liter and 1 20 liter bag for packingon a trip where my bag/luggage would be open to the elements in my truck bed. Find out these work great as organizers for regular packing in a duffle bag. I also camp so I bought another 20l in bright orange for my go to emergency kit In my truck. It will carry my down bag and jacket matches and I other emergency gear.I like that these are light as I have had multiple shoulder surgeries and the straps help me. Looking into packing some of my camping gear in multiple bags so I can have them color coded for different equipment. Thanks sea to summit for done great bags.
I really like these dry bags. I use them for canoe tripping and the oval shape fits perfectly in a portage pack and leaves less wasted space in the pack. Also, the lash loops make it easier to remove from the pack and while I haven't used it, the attachment points for a shoulder strap could be really useful for day trips. The construction is top-notch. I've used dozens of other dry bags and these seem to be tougher than all others I've used. The material is strong and puncture-resistant while not being thick and heavy. I have been paddling and using dry bags for over 30 years and also worked in the outdoor retail industry. As far as I know, these are the best dry bags on the market.
Really disappointed in the performance of this "dry bag". I just returned from a 6 day canoe trip (BWCA), and this was the only bag that really didn't hold up! With multiple portages throughout our trip, we carried the bags over various terrain but with minimal abrasion from rocks or the ground. The dry bags made of "500-denier waterproof, polyester PVC" performed great - no issues with any of them. My inexpensive dry bags made of "190D diamond ripstop polyester" did pretty well. I was very surprised to see by the end of the trip, this bag's 420D nylon fabric TPU did not hold up well - the sides did fine, but the black bottom was easily damaged by incidental abrasions with rocks or the ground and developed a small tear and lots of small holes. Really unacceptable ... MoreReally disappointed in the performance of this "dry bag". I just returned from a 6 day canoe trip (BWCA), and this was the only bag that really didn't hold up!

Really unacceptable for a dry bag to of this size and description to not be more durable. The product description says it's "durable, strong and abrasion resistant..." and "...great choice for rugged watersports such as kayaking, canoeing and whitewater rafting" - it's simply NOT. They are lightweight, maybe suitable for lining INSIDE a pack or within a kayak hatch, or for rain protection for bikepacking. They are not suitable for direct exposure to any abrasion, the holes from the slightest abrasion means they may stand up to rain but not any real / consistent exposure. I'm a former rafting guide, kayak trip leader, and have experience in multi-day kayak and canoe camping trips. I expected better from the Sea to Summit brand and am puzzled by all of the positive reviews.
I wanted these bags for bikpacking rather than river duty, so my priorities may be differnt from others. I wanted a medium weight bag with a sturdy loop to ensure that it stays put on a rear rack. The bag seems quite sturdy and waterproof without being extremely heavy or stiff, and the quality and design seem excellent. I haven't had the chance to use it on a trip yes, as it's still winter in Idaho, but I expect it will work well.
The Big River are my go to dry bag gear for kayak/canoe camping. I tried another brand to get some perspective and returned it right away. I have several sizes including the 5l, 35l and now 20l. I previously got a 35l clear rubber/plastic one, but the plastic creates friction that makes it hard to slide in the dry hatch. The big river bag is easier to work with. It’s durable and the lashes on the outside are handy for a number of purposes. I’ll probably get another 20l. The 35l fits my sleeping kit contents. The 20l for food and clothing. 5l for flashlight, knife, lighters, toiletries.
