This is an awesome backpack that is great for one-day ascents or trips. I just recently used it on a two week climbing trip, and it was perfect for bringing up to the cliffs each day. I was able to fit all my climbing gear in it, plus some food and extra clothing. There is also tons of water space between the pouch and the two water bottle holders. It also kept much of my gear dry when the weather got crappy, especially in the front pocket that has a waterproof zipper. Another cool feature is that there are no straps bouncing all around when you are hiking, because they can all be bound up by built in hook-and-loop strips. This is a great pack, and I strongly recommend it!
