great drybag; could use some tweaking

  • Familiarity: I've used it several times

I'll start off by saying this drybag is solid. I've taken it out for a couple of week-long trips and it provides all the functions that I expect of a drybag: the construction is good, it seems like it will hold up for a long time, it's easy to pack and, most importantly, it keeps your stuff dry.

That being said, there are a couple of things that would take this drybag from good, to stellar. I have the 70 liter, which I find is more that enough space to pack a week's worth of stuff. I personally think that the proportions of the bag are a touch off, though, in that the bag is a little too tall and skinny so it's difficult to unpack something towards the bottom without unpacking your entire bag (disclaimer: I just transitioned from a lateral bag so this could very likely be a personal prejudice). The only other feature that I would like to see is a handle at the top of the bag. The backpack straps are great for carrying this bag around camp or on short hikes but I think a hand-hold loop at the top of the bag would make it easier to rig in a gear-boat.

All in all, though, worth it.

Unanswered Question

hi I would like to know the height of a 35L bag, I am quite short (5"3) and need a bag that doesn't fall to my knees when I carry it. thanks!

If you don't mind me asking. What all were you able to fit in your 35L for a week? I'm planning on picking up one of these and trying to decide on a 35L vs 70L. I have clothes, tent, sleeping bag, and pad to haul.

All day.

  • Familiarity: I've used it several times

Just bought the 115L for canoeing into the bwca - I liked it a lot.

It was more comfortable than I expected on the portages. Kept everything dry in some pretty heavy rain with no issues.

Also, detachable back straps were a nice feature.

Works for me!

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

I have only used this bag on one canoe trip into the BWCA so far but thought I'd give my two cents on it.
When the package arrived I immediately looked for damage due to the folding/packaging of it as other users have spoke of. Low and behold, there it was. The discoloration of the material in the folds was very noticeable right away. After a thorough examination, and given the fact that I had no time to return it, I decided to go with it and see if the material had actually been compromised to the point that there would be problems. No such luck. The bag held up to some fairly good abuse of being thrown in and out of the canoe and shuffled around the campsites.
I was able to fit enough gear for my wife, my daughter and I for the weekend(and we brought the kitchen sink too if you know what i mean!). This did not include the food as i always keep that in a seperate system.
Overall the bag seemed to hold up and worked great to keep everything dry and clean as it did rain most of the trip. These bags obviously don't breathe so if you put your tent/tarp in there wet, the condensation will get the entire contents of the bag wet if you do not pack your stuff into seperate systems in lightweight dry bags. Such as putting your clothes in one, sleeping bag in another etc.
As for being comfortable, make sure you think about how you pack it and it is not to bad for the shorter poratages of a mile or so. Anything longer, depending on how you pack it could get a little uncomfortable as the strap system is not really up to speed as far as backpacking is concerned.
Improvements to the strap system and the packaging damage issues would help this bag a bunch!
All in all, it worked for me!

Works for me!

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!

  • Familiarity: I've put it through the wringer

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!
