Why We Like The SealLine Boundary 35-115L Dry Pack

The SealLine Boundary 35-155L Dry Pack protects our gear and frees up our hands. The roll-top closure, welded seams, and coated material give our layers, tackle, phone, and camera a water-tight barrier against splashes and rain, while the removable padded harness gives us the option of carrying our gear backpack-style when we're out there on the water, trekking in the rain, or traveling in the tropics.

Sturdy and dry

The pack is really sturdy and secures on the back really nicely so the weight distributes well. Supremely water proof. Would not recommend having to much weight in the pack if stringing up to keep away from animals. Bark of a tree scuffed off a little bit of the outer layer.

Great pack for canoe tripping.

Used my Boundary pack for several multi day canoe trips and the 65L was a perfect size for myself and my small dog. Loved how strong and yet supple the material was and how supportive the harness was without the padded belt. Only improvement I'd make is perhaps a few anchor points to attach an accessory pouch/bag for quick to access items. Will probably glue them on myself for the time being.

I trust SealLine with my valuables

This bag is not too big, not too small. I had been using the kind without backpack straps and they would get awkward to carry. So I looked for ones with backpack straps and picked this one. I used it on the Tribal Canoe Journeys in the PNW. Kept everything dry. I like how there's a strap and buckle across the top to strap down an extra item like a sleeping bag or cushion. Great bag from the best dry bag brand. I trust Sealline from Cascade Designs.

Great pack . Carries loads

Great pack . Carries loads of gear for a short trip. Relatively good back pack but I wish the waist straps were more substantial .

Bomber bag!!!

I took this bag canoe camping and it was a wet weekend. Everything stayed dry and it packed well in the canoe. Plus, it was easy to handle. I definitely suggest this bag for longer trips, and any boating adventures!

Alaska proof

I was gifted a 35L Boundary 9 years ago as a safety award from work. I've owned lots of dry bags and handed out Alaska sized doses of abuse to my bags including month long sea kayaking trips, white water runs, hunting and using the packs to haul massive loads of freshly killed salmon....like 80 lb loads of salmon. I am absolutely impressed with the quality of the Boundary 35L. I expect (and accept) that sharp rocks and heavy loads will destroy dry bags but this pack as been the exception. Definitely buying more of these things...if for no other reason than make it so my wife can also have haul loads of fish up the canyon wall!

I took 2 of these

I took 2 of these bags on a 6 day canoe trip through the Allagash Wilderness Waterway and they performed superbly. Very rugged and well built!

Stash pocket?

I wish it had an interior or exterior stash pocket for the little things in life.
