The Black Diamond Revelation Pack is a great all-around ski mountaineering pack, especially if you want to have one pack that will do everything. The design is very clean and seamless, but the construction is burly. No major competitor exists for a similar pack. Osprey and Arcteryx both make packs for ski mountaineering, but the set up and construction is comparatively awkward. In some ways, Black Diamond can be considered to have cornered the market in terms of ski mountaineering packs with a similar pricepoint. Given that this is the case, I was eager to get my hands on the Revelation and test it out in its intended environment.
