Deeply creased from folds for packaging

  • Gender: Male
  • Familiarity: I returned this product before using it

I bought this to pair with my older bag of the same size. (My "older" is actually from the newer Black Canyon line.) They both are packaged similarly, and show some permanent creasing from the hard, compound folds. This one, the one currently being reviewed, actually shows quite a lot of light thru the creases. If it is still reliable when pulled so thin, don't tell me. I'll kick myself for portaging the excess weight.

Sending this one back and picking up another from the newer model locally. Even if I have to eat the return shipping (and pay the difference for the newer, PVC-free model) I'd rather not have to patch or worry about a brand new bag. Too much to do in the nerve-wracking time before a week-long, unsupported canoe trip on whitewater that will be mostly full of guided rafts.

Be Aware of the Shoulder Harness

  • Familiarity: I've used it once or twice and have initial impressions

This drybag is big, seems well made and will seal as well as any other drybags of similar style. One thing to note is that has a beefy shoulder harness AND waist belt for use in carrying the bag "backpack" style. Be sure to take a close look at the pictures. This seems a little overkill to me. I'm only carrying it from the raft a few hundred feet to where I'll pitch my tent. Usually, I'll only put one arm in the shoulder harness to do this. This harness looks like it's built for someone to carry the bag a significant distance. Also, it is somewhat difficult & time consuming to remove and re-attach. Overall, a good bag for the price Backcountry is currently selling if for.

Great Bag for a multitrip

  • Familiarity: I've used it several times

I bought this bag for a 5 day trip and it worked beautifully. When when fully submersed it kept my things dry, if you can pack it right that is. I bought a 70L and that was enough to pack for 5 days, sleeping bag, tent, jacket, camp pillow, and misc. Perfect size and best if you are doing any river trips.

Killer bag

  • Familiarity: I've put it through the wringer

These bags are awesome.. The original SealLine Material is pretty bombproof. There are always abrasion spots no matter what dry bag you use- just be ready with the aquaseal. Beware of the new SealLine "Black Canyon" material- its more environmentally friendly, but had a crack along the fold after the first use.. badnews, and not waterproof. These on the other hand hold up against quite a bit of abuse- paddle trips, rainy bike rides, fishing trips, airplane carry ons and checked bags. Awesome bag.

Great Dry Bag

  • Familiarity: I've used it once or twice and have initial impressions

Ok, so I didn't even know what a dry bag was until I purchased this for a summer camping/canoeing trip! I ended up buying the 70L in black which gave me plenty of room to keep all the things I needed for 8 days. I even fit my rolled up sleeping bag and sleeping pad in there too! The straps made portages easy (even for me - I'm a fairly small teenage girl, and the bag was almost bigger than me!) It also poured rain for a lot of my trip, which meant my bag was often sitting in a puddle of water in the bottom of the canoe and being pummeled with rain. None of my stuff ever got wet, so it appears to be leak proof. I would highly recommend this purchase!

My SealLine Boundary gets used primarily on boating trips - latched down on a raft or on the deck of a small boat. I've had it for several years and seems really durable. These almost seem bigger than they are - easy to load and the 70 liter will be the only bag you need to hold all your gear for a week - if you leave the kitchen sink at home. I've never canyoneered in it so can't say for sure how waterproof it really would be if submerged a lot during the day. My experience with these types of "roll-over" closures is that you can never guarantee water-tightness. But for a lot of splashing, these do great and have no plans to change this for my boating purposes. If 100% water-tight is your goal, check out Watershed dry bags.

Solid bag, very Dry

  • Familiarity: I've used it several times

I've used these a number of times through rental canoe outfitters. These have never leaked on me once and it was a rental so you know people abuse the heck out of them. The suspension is pretty primitive but what do you expect from a gigantic vinyl sack. It beats the hell out of carry it like a big garabage back though especially if you're portaging. If you're carrying a lot of weight you might want to wrap the shoulder straps with towels to give some extra cushioning because the hip belt it pretty much useless except for just keeping the bag in place.

Worked well in Zion

Good dry bag. Kept my gear dry on an overnight through the Zion Narrows. As mentioned below, the material is a little thin, so need to watch the rough rocks and other objects.

I'd go with the 70L. I'm assuming that you'll have more than just your camera. The 35L might not fit your bag because it's so long.

Boundary Dry Pack

For the price, this is a really solid dry bag that performs as well as any dry bag could with moderately taxing use: it keeps things totally dry.

A few notes:
- I did not take this bag canyoneering or on any activity that would test the durability as aggressively as canyoneering would, so take my review in that context. This bag accompanied on a multi-day steelheading trip in the Pacific NW with lots of rain.
- No exterior water bottle pocket is a bummer (though I understand why there isn't one). And for similar reasons, no exterior lash points on the body of the bag is also a bummer.
- Big. The thing is big. Even the 35L is cavernous. I used it as my carry on bag for the same trip and with a whole bunch of work stuff and laptop in it I still didn't even come close to filling it up.
- I really think you're going to struggle to find something better at a similar QPR. Unless, you want something smaller and more streamlined or with more organization features, this is really tough to beat at $67.

This bag does ok. The material is actually kind of thin. Mine has worn out along the creases very quickly along. I bought it with the intention of canyoneering which truthfully, is probably more than this pack can handle. It is probably great for paddling but when you start to mix this material and abrasive sandstone, things go bad quickly. I love sealLine but I think I'll stick with a smaller dry bag inside of a regular pack for my future canyoneering trips.

worth every penny

i haven't tried putting these in water- but they were worth the money for the peace of mind we had on our camping trip. The back straps make them so easy to carry to the campsite. We're very happy we made the investment!

Questionable durability

My 70L bag just arrived, and unforunately is showing significant wear at the creases where it was folded in the packaging. The wear/holes almost penetrate the entire thickness of the viny, which doesn't instil confidence that this bag will show durability in the field. I am returning, and think I will look at other options/manufacturers. It's possible that I just got unlucky with a defective bag, but based on other reviews elsewhere it seems that premature wear and failure at the crease points is not an uncommon problem. Otherwise, the design of the bag is nice.

Great bags

My wife and I Bought the 70L and used it on a 4 day trip into the BWCA. It holds a ton of stuff!. The thing i liked most about it was the straps that go over the top are extra long so we strapped two full size camping chairs and two air mattresses on top of the pack after it was sealed up. Sure made for an easy portage that was 3/4 of a mile long with 4" mud puddles,down trees, hills and slippery rocks! I love SealLine!

Love having a dry bag with straps!

Love it. For years, I've been hauling around my old SealLine with no straps. Wish I had gotten this sooner! This pack is awesome, and pretty comfortable. Everything perfectly dry in all SealLine products for years. I own the 35L and 70L.

My only complaints are that the strap positions are a little to high, for 2 reasons. 1) I am pretty small (5'4"), and the bottom of the bag in both the 35L and 70L hits the backs of my legs while walking. I would rather the straps were lower and the bag went up higher, like a camping pack. 2) Sometimes (ok, almost all the time) I have just too much gear to fit in the 35L, but not nearly enough to fill the 70L. Because of the high strap placement on the packs, I can't just roll down the top of the 70L to make it whatever size I want, so it ends up loosely packed and awkward.

Decent Dry Bag

This dry bag does its job of keeping your stuff dry. It's not as thick as other ones that I've used but seems durable enough. The straps on it come in handy when portaging as they free up your arms to use. I was able to fit my 2P tent, sleeping bag, pillow and some fishing gear into the 70L bag and still had a little left over room.

Great Bag

I have the 115L and I love it. It is durable, definitely waterproof, and fits tons of stuff. The straps are nice for carrying it to the boat. I wouldn't recommend using it as a backpack as there is no structural support for your back.

Could be good

I bought this to take on a hike through the Zion Subway and Narrows and keep my camera safe. I haven't actually tried this out, but the material feels like it can take a beating.
I decided to go with so that I can strap my tripod to the back and keep water easily accessible.

Killer bag!

Just bought a 115L after using a friends to shuttle loads to the base of a wall. I was impressed with the durability and pleased with the ease of loading due to the wide mouth. We were shuttling loads of approximately 75lbs. With loads that heavy the pack isn't going to be comfortable for extended periods but is plenty tough to handle it. They are also a great option for gear caches where you need to seal out the elements (ie, Patagonia and the greater ranges).
