The Outdoor Research DryComp Summit Sack is both a waterproof stuff sack and an ultralight backpack.

The Outdoor Research DryComp Summit Sack keeps your clothes or sleeping bag dry and converts to an ultralight backpack when it's time to bag a peak. The DryComp Summit Sack's Hydroseal-coated Antron nylon is seam taped to make it fully waterproof. A roll-top closure on this Outdoor Research compression stuff sack holds out moisture, and compression straps shrink your load. When you pack up on summit day, leave your huge mountaineering pack behind. The 12.2-ounce, 1885cu inch Summit Sack has two backpack straps and holds all your necessities for the final push to the top.

A game changer

  • Familiarity: I've put it through the wringer

From the Grand Canyon to the Grand Teton, bring it along. I have dreamed about a pack like this on many occasions and now am a proud owner of one and it has not let me down. It seams as though i would have destroyed it or at least put some holes in it, not yet. I am not too concerned as I have an OR guarantee behind it, the best in the industry.

How small can you compress this bag when empty?

Responded on

pretty small. i just rolled it in a store to a tube shape of 11 inches long by about 4.5-5 inches in diameter. you can probably compress it a bit smaller too.

That sounds about right!

A three fur

My buddy has had this pack for two years now and has sworn by it on a couple of rainier climbs , the olympics, and Adams. I fell in love with it because I'm a stickler for weight and often compromise some functionality in order to save on it. Not with this bag. It's a three fur. Love that it packs away small. I use it as a pack liner for half my gear, the stuff I don't want to get wet. For the summit dump that out, pack the essentials, an away we go.

One of a kind product?

Dry bag/compression sack/day sack. If there exists another product combining all of these functions I am unaware of it.

I've got a nice little OR compression dry bag that packs real small into an internal pouch. Problem? No shoulder straps. Ditto on the compression sacks I have -- great for stuffing gear, but none of them shoulder straps.

(And of course I've had plenty of regular day packs over the years, but none of them are dry bags!)

So yeah, great combination of functionalities. So far it's treated me well.

DISCLAIMER: I have not taken this on the river yet and cannot vouch for it's dry-ness. Hence the 4/5 stars.

a real "go to" piece

I've had this now for over a year. Initially bought it for the idea of having a stuff sack for packing soft goods when traveling and simple, no-frills day pack for quick climbs. (I'm not a regular boater. I did use this on my one and only sea kayaking trip for clothing. Two day trip. All stayed dry.)

Man o man, if this bag has not turned into something else! I still use it to pack clothes in all kinds of travels. It has served as a summit pack and a light day pack. I pushed it to the absolute limit on a volunteer re-bolting effort and hauled it with extra batteries and bolts up a 90 ft of sandstone. It did pick the mesh a bit on the outside, but this has never progressed to unravelling and remains fully functional. The size is generous. The compression straps are ingenuous in that they double as an ultralight waist belt. The multiple daisy chains on the outside allow you a lot of low profile options for hooking the Summit Sack up with more stuff or to a primary load.

This piece has really filled a niche for my gear stache. I guess the tell-tale recommendation comes with "If anything happened to the bag, I would replace it despite cost."

Better as a dry bag, OK as a pack

I was carrying a summit bag inside my big pack for the hike up to base camps. I also had my down sleeping bag stuffed inside a stuff sack line with a garbage bag. When I saw this product, I thought I had found a way to reduce the stuff sack/garbage bag and summit pack into one bag. In short, it worked with the added benefit of now having a waterproof summit bag. However, as a compression sack, it compresses a bit wide from what I'm used to. As a backpack, it's frameless design makes it important to pack it well and keep it light. The mesh pockets are nice to have for a water bottle and GPS. The shoulder straps are narrow! I put about ten pounds of gear in the bag for a test hike and found it started to dig into my shoulders after about an hour. The narrow waist belt helped alleviate that a bit but don't expect pack performance out of this bag. I'm going to experiment with a closed foam rectangle in the bag to help the load feel better. Had I seen it earlier, the REI Jet UL Pack may have been a better match for what I was looking for. Although not a waterproof compression sack, it can swallow bulking insulating layers and probably carries better - at least it did in the store. All said, this bag is worth the money if for nothing else than the flexibility it offers.

daypack yes

I bought primarily to have as a summit sack, hoping it could replace my compression sack and perhaps also do well as a daypack. Two out of three ain't bad and I would add that it seems substantial enough for a summer overnighter bag.

The cons are that its really too big to be effective as a compression sack except for shrinking large bulky sleeping bags to put in large expedition packs and even then its really only capable of minor compression due to the way the straps are setup. Would also be nice if it had a bladder sleeve. As others have said, it really could use a chest strap, but I found this to be a relatively easy fix with a Velcro strap.

The good is that the material is pretty substantial (not sil) and it seems to sit pretty well on my back whether its a small or large load. The shoulder pads are more substantial than I expected and the side pockets are plenty large - enough for a 32oz Nalgene to sit down in it well. The side pockets are what sold me as most day/summit packs are either pocketless or would not roll up to pack in a larger pack as this one does.

Its a bummer having to make room in my pack for it as that is not what I had planned, but it seems to be my best choice given function and value.

great concept but fragile

This pack has great potential for ultralight adventures. Bought mine for rafting but am using it as a backcountry ski pack too. Still happy with it even though I have a hole and blew a seam almost instantly.

OR products have a lifetime warranty and I've read blogs about how OR has repaired down jackets free of charge that some ones dog chewed a hole through. I'm sure they'd fix it for free
