SealLine Boundary Pack 70 Reviews:


Excellent, protective dry bag

I was very fortunate to recently enjoy a seven day canoe journey on Northern Maine's Allagash Wilderness Waterway with a SealLine dry bag. It is a sturdy and effective gear storage bag. It kept everything bone dry. Having the backpack carry straps is indispensable for portaging. You can't go wrong with this product. Make sure to get the largest size you need. A 35 liter is too small for a seven day canoe trek, so go with the 70 liter. Folding it from the top to properly seal out water reduces the capacity, so again go with the larger size. You will be pleased with this great dry bag. The Allagash is truly magical. Do it and enjoy adventure, beauty and peace. Happy paddling!

I have the older model of this bag and have seen the new one. The only difference is the new straps look great and would probably feel good if the bag was nice and heavy. I used the old version on a week long canoe trip and it was perfect. The only reason to not buy this is if you are an idiot

Great for Portaging

This dry bag pack should be very helpful in consolidating gear and clothes when canoeing. No more concerns about getting stuff wet or dealing with multiple bags. The price is much less when compared to other brands of the same size and when you get it at a discount, this is a steal.

Smartest buy ever

This all purpose bag has great storage capacity, is extremely durable and very easy of use. I use it for canoe trips down river as easily then for my scuba or camping. It is not just multi-purpose but very effective. This bag is a must for anything outside the house.

Big Guy

Large enough to fit everything you need for a 7 day trip down the Saco river in ME. It gets a little on the heavy side but 7 days of gear is 7 days of gear no matter the packaging

Great dry bag

This product was great for overnight raft trips - it held my tent, sleeping bag, thermarest and clothes etc... with no problems.
