Outdoor Research DryComp Ridge Sack


Outdoor Research makes its DryComp Ridge Sack for mountaineers who want to travel light on summit day. The waterproof backpack is roomy enough to carry your essentials and comes with ice-ax loops and a large mesh pocket that can hold a hydration bladder, a shell jacket, or other gear.

I tested the Ridge Sack a few dozen times this summer. I know what you’re thinking: a summit pack in the Adirondacks? In summer?

Well, the Ridge Sack is also ideal for paddlers on day trips. I brought it on nearly all of my canoe excursions this year. This tough nylon pack, with its watertight seams, always kept my stuff dry. Like traditional dry bags used by paddlers, the Ridge Sack is closed by rolling and buckling the top. When you need to portage, you wear it like a backpack.

The Ridge Sack isn’t overloaded with bells and whistles. (Actually, there is a whistle on the sternum strap.) Its features include the ice-ax loops with associated shock cords, the mesh pocket, shoulder straps, waist belt, and two compression straps. Otherwise, it’s just a big sack (34 liters) that you can wear on your back. For days trips on the water or up an alpine slope, that’s all you need.

Priced at $119, the Ridge Sack is the most expensive of three waterproof summit packs made by OR. The DryComp Summit Sack is as big (36 liters) but costs only $65. The compression straps convert to padded shoulder straps. The Dry Peak Bagger is the smallest (29 liters) of the packs and costs the least ($55). It includes independent shoulder straps and a large exterior pouch.
