Description

Ideal for kayaking and canoeing but suitable for backpacking trips that call for maximum protection, the mid-weight Sea to Summit Big River Dry Bag is highly durable, extremely abrasion-resistant, and fully waterproof.

The dry bag’s rugged 420D nylon fabric is highly durable and has a TPU lamination to guarantee protection from moisture. Fully-taped seams further ensure weather protection and reinforced stitching bolsters strength. A waterproof Hypalon roll-top closure provides wide-open access to the bag’s interior but battens down the hatches by using an internal stiffener to create a secure seal. Oval shaping at the bottom of the dry bag provides structure and makes packing easy.

The Sea to Summit Lightweight Dry Sack is available in a wide array of color options and 3 Liter (7” x 4” x 11”; 2.5 oz), 5 Liter (7” x 4” x 15”; 2.9 oz), 8 Liter (8” x 5” x 17”; 3.5 oz), 13 Liter (9” x 6” x 20”; 4.2 oz), 20 Liter (11” x 7” x 24”; 6 oz), 35 Liter (13” x 8” x 28”; 7.7 oz), and 65 Liter (15” x 10” x 33”; 10 oz) sizes.

  • TPU laminated fabric with 10,000 mm waterhead
  • Super strong and abrasion resistant 420 D nylon fabric
  • Waterproof, double stitched, reinforced, tape sealed seams
  • Hypalon lash loops for secure attachment or stacking
  • Waterproof Hypalon roll top closure does not wick moisture
  • Space saving, low profile, streamlined shape
  • Oval base resists rolling - stays where you put it Proper Use:
  • Any roll-top dry sack must be closed properly to ensure water can't get in. Begin by folding the Hypalon strip down first and be sure to have at least three rolls before closing the buckle.
  • Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
  • Sea to Summit recommends that sensitive electronic devices be 'double bagged' (i.e. putting electronics inside one dry sack then placing this inside a second dry sack). For maximum protection, the use of a waterproof hard case should be considered.
  • Not intended for situations where dry sack will be submerged under water.

Durable and gets the job done

This bag is durable and does what you need it to. I've used this backpacking and it's held up to rain and river use.

Perfect solution for my cold weather kit

Likes

I don't always want to carry my cold weather emergency clothes bundle in my pack. I wanted a compression sack that I could attach to the outside of my pack to fix this problem (and attach or detach the cold weather kit, as needed). This sack needed to be durable and not the same as a regular compression sack. Enter the Big River Dry Bag from Sea to Summit. This bag has some durable, purpose-built loops that let me lash it to my frame, solving a problem regular compression sacks have--"how do I attach this thing to anything?". Short answer, you can't. At least you can't attach regular compression bags. This dry river bag solution shrunk my clothes down to 1/2 the size they were before. I wonder why more people don't just use these instead of compression sacks? Perhaps it is because they are slightly heavier, I suppose. But they're sturdier instead and more versatile.

Bags are smaller than you think

Light

Bags lose a lot of storage due to requiring 4 folds to ensure water tightness.

Keeps things dry

Tough and easy to clean if you get muddy.

Maybe a bit overkill, but nothing wrong with that.

Great heavy-duty dry bag.

Likes

The size of this bag is perfect for me. 20L sounds really big, but once it is folded down, this would be a useful size for a couple of medium sized electronics. I have a Tenba 10 camera case that fits perfectly inside this dry bag. I have my small canon SL2 DRLR, a canon 70-200 F4, and tokina 11-20 F2.8 that fit inside. the dimensions for the case are 6x9x10in and it's a pretty close fit once I roll the top 3 times. I used this and one other dry bag to keep my camera setup safe through some pretty deep water in the Narrows in Zion. No dry bag is 100% waterproof, but anything less than prolonged submersion and I would trust these. I used this as a part of my "double dry bagging" setup along with the Sea To Summit lightweight dry bag. This things seems very durable and is very confidence inspiring for use with expensive electronics.

Dislikes

Because of the thickness and durability it doesn't pack quite as nicely at the lightweight drybag, but that's a tradeoff that I'm willing to make for any abrasion heavy environment.

Water in bottom of bag...

Likes

Price (they were on sale) and the larger size, perfect for a couple of sleeping bags stacked on on top of the other...

Dislikes

I bought two of the 65 L Big River bags and we recently took them out on an overnight float trip. Neither bag was ever submerged, dunked or exposed to any unrealistic amount of water in either the canoe or kayak. Nor did we abuse them in any fashion. One was fine, the other had water in the bottom of the bag when we got off the river. Not down the sides, just in the bottom. Luckily, I'd put gear in water-repellant compression bags, so nothing was ruined. However, I won't say I'm not disappointed in the quality. I really appreciate BCE's return policy, as the defective one is going back. Time will tell with the other bag...

Great bag, bigger the better.

Likes

The color. The loops for straps if needed. The weight.

Dislikes

Got a little water in it after dunking it completely with about 8 turns at the top of the bag. But my friend sealed it so not sure if it was closed properly.

Good dry bag

Likes

I have been using these bags for a couple trips now and like them very much. Well constructed and easy to use. The biggest thing that I like about them is that they are softer than some of the other styles of waterproof bags. I am guessing that this will make them less durable over time but I have no indications right now that this bag will not perform well for many years.

Great durable dry bags!

Likes

Nice size, fits nicely in packs and seals well. I've not purchased dry bags in 20 years or so; I suspect these may last even longer than my last ones (the fabric seems more durable).

Dislikes

For canoe portages I wish they were lighter, then I'd be giving up durability.

Packaging not recyclable!

Likes

Well made. Performs the intended function.

Dislikes

Seriously? The plastic package for this dry bag is thick and heavy. I looked all over for a recycle emblem. None! How can a company that focuses on outdoor equipment not be more environmentally conscious? Two suggestions: 1) Reduce the packaging and 2) Make it recyclable and clearly marked as such.
