Sturdy yet lightweight dry bag
February 10, 2011

Purchased this bag for a trip to Zion, and loved it - it's very lightweight, but the fabric is surprisingly sturdy. Like everything else OR, it's really great quality and gets all the details right without overdoing anything. I love this brand, and this bag was another good purchase. The only minor drawback was that the bag doesn't have a hip strap, which the slightly more expensive version does. In some situations it's nice to be able to ditch it quickly, though, so I don't view that as a significant drawback. I'm a careful buyer, but I would recommend this to anyone.

Pros: Great design, Build quality, Lasts forever, Performance, Ease of use, Great value

Nice light waterproof day pack
January 31, 2011

Very light with good construction and materials. Tested my new drycomp summit sack at my farm stuffed full of newspaper in medium snow. Contents stayed dry! Should straps are small and narrow would not be very comfortable with much weight but would be great for a day hike or ultra light weekend trip. I love it will be using it for a day pack next fall.

Pros: Build quality, Ease of use, Great value, Cons: narrow shoulder straps

Light Daypack
February 25, 2007

This 12 oz waterproof drybag, is also a backpack. I can fit a weekends worth of gear (hammock, tarp, food, clothing), put 1L water bottles in the side pockets, and stay overnight. I had to add a sternum strap, but it carries 15 lbs comfortably. A very unique pack.

great pack
May 09, 2012

This is the ultimate pack. It may not be the best in terms of the snug fit hugging your body but that is overrun by its ultimate versitility. You can really load this thing up with a fair bit of gear compress it down stow it in whatever craft you are in, sail paddle float, and when you get out you can throw it on your back. Unlike that compresion stuff sack you may have done that with in the past this will not cut into your shoulders and it will keep your gear dry in the down pour. Go get one

Pros: Great design, Build quality, Ease of use, Great value, versitle

My favorite daypack by far
July 07, 2011

The Drycomp Summit Sack exceeded my expectations. It was a bit sturdier than I expected it would be. I can comfortably carry around 14 pounds in this pack on day hikes. (I'm six feet tall and lean.) As long as you roll down and fasten the top, it holds its shape quite well, even when not completely full. On backpack trips, I leave my other 8-ounce dry sack at home and use the 12-ounce Drycomp Summit Sack instead to stuff my down sleeping bag. (The Drycomp's compression straps do a fairly good job compressing my bag down to a reasonable size.) The 4-ounce difference is a good tradeoff: once at base camp, I unstuff my sleeping bag, put it inside my tent and use the Drycomp for dayhiking. For only 4 additional ounces than I would normally carry, I have a 36-liter day pack along for the ride. At night, I stuff my down vest in to the Drycomp Summit Sack and use it as a pillow. With the back side facing down, the straps are out of the way and it becomes a reasonably comfortable pillow case. The stretchy side pockets (which, thankfully, feature elastic drawcords) are each big enough to accommodate a liter-size water bottle and one smaller item -- a small umbrella or a bottle of bug dope. There are no other outside pockets -- and none with zippers -- for carrying small items. It's worth the trade-off and not such a big deal if your pants have plenty of cargo pockets to carry GPS, map, pocket knife, whistle and snacks at the ready. I haven't had the Drycomp Summit Sack in a downpour yet, only a light shower. But I love the promise of weatherproof construction it offers. I can leave my garbage-bag liner at home (reducing my 4-oz weight penalty even further). Outdoor Research makes quality gear, and the inside construction and detail for this pack inspires confidence this pack will perform well in wet weather. I'm looking forward to using the Drycomp Summit Sack on an alpine mountain climb next month, where the daisychain loops (for carrying biners and belay device) and ice-axe loops will come in handy. Light weight, relatively large capacity, quality build, waterproof construction and a great price point make the Drycomp Summit Sack a winner! I love this innovative pack!

Pros: Great design, Build quality, Performance, Ease of use, Great value, light weight

Fantastic Product
March 18, 2010

Great Bag- lots of space in the main compartment and a very water tight seal. Well worth the money.

Light and multi-functional
June 30, 2009

I bought this product because of its versatility for an around the world backpacking trip. I'm going to use it as compression sack/drybag inside my larger internal frame backpack, and then as a secondary bag for two-three day trips and airplane carry on. As a dry bag it appears to seal very well. It has tapped seams and the material appears durable. As a backpack, it has a large main compartment volume good water bottle pockets. It lacks pockets for organization and compartmentalization, but that's a trade-off for weight and packed volume that's useful for my purposes. As a compression sack/dry bag, it does a decent job. It holds my tent (no poles), sleeping bag, sleeping pad, hammock, sleep sack, towels, and compresses it so that it all fits into my backpack's bottom compartment. I haven't tested it in the field yet, but my impression so far is that the quality is decent and about as durable and comfortable as it could be while minimizing bulkiness and weight. I also have the OR Dry Peak Bagger, which is much lighter, but I don't like it because the material and straps are too thin and fragile.
