User Review: Outdoor Research Dry Peak Bagger
Price Paid: $50
It's kind of a specialized pack, but if you need these features, it's a great product.
Firstly, it's waterproof. Fully waterproof, that is, with a roll-top closing system just like the kind used in dry bags for kayaking, canoeing, etc. It's not just water resistant. This thing will keep your stuff dry in a total downpour; or submerged in a stream/lake/ocean.
Secondly, it's light. Feather light. By itself, it weighs almost nothing.
Thirdly, it actually has some nice, thoughtful features. The people who designed it thought it through. It has one main pocket, and a double-duty exterior pocket - with a tube/strap setup designed to secure an ice axe.
On the down side, its lightness is due to the fact that it is made from very light fabric. So, I would not expect this pack to last a long time. I would certainly worry about subjecting it to a lot of abuse. I doubt it would hold up to prolonged scraping against rock faces. So I'm going to be careful with it. It will only be waterproof as long as I keep if from getting ripped/punctured.
And, it has no suspension system to speak of. The shoulder straps are pretty comfortable as long as you are not carrying anything heavy. There's nothing in the way of a back-pad. There's no waist strap. We're definitely talking minimalist here.
I've only used it a little bit so far; and so far I love it. Keep in mind its limitations; use it for specialized situations and it's superb. It's even relatively inexpensive. Small, light loads (15 lbs or so)? wet conditions? Little chance of sharp, rough contact? Great!
