Perfect for 1-2 day tours
I've used the Black Diamond Revelation a few days this year and have been really happy overall. I use the smaller version, which is ideal for single-day tours or supported multi-day trips in the BC. Don't expect to pack much food, a bag, or tent- just the essentials. The pack fits really well, has easy access to avy tools, enough space for extra down layers, socks, gloves, etc, and a top pocket for the small stuff, not to mention a couple of nice pockets on the waist belt for snacks or maybe a radio. The hydration compatibility is mediocre, expect to cut the hole bigger if your hose is insulated. For the most part this pack is bomb-proof, well designed and really durable. It's definitely been made with skiers in mind and I would not recommend it to someone looking for a camping-style backpack or to snowboarders.
