Alex Chocholousekwrote a review of Sierra Designs Ministry 40 Backpack - 2441cu in on December 9, 2013
Familiarity: I've used it once or twice and have initial impressions
First off, while not the lightest alpine-style pack out there, this thing is made of some super tough materials. I like the philosophy Sierra Designs used in creating this pack - it's old-school toughness (nice, tough, cordura-like fabric, tubular webbing on haul points) mixed with forward-thinking features. I really like the ice tool attachment system, very secure, and the crampon pocket is tougher than heck. My one complaint is that the "brain" is maybe a bit over-designed - there is a fleece goggle pocket that folds out (which I love, by the way) AND another zippered pocket on the inside of a overly (for the pack size) large "brain". I'm not much a "brain" user anyway, so I strip it and save some weight. The cinch collar material at the opening of the pack is super tough and plentiful, so it works well for this. All in all, everything you could possibly want in a cragging/alpine pack is here, plus this thing will last a long time, from what I can tell. Highly recommended.
Also, for what it's worth, the "rock" color - which looked black to me on my computer screen online, but is actually a medium-dark gray - looks great!
