3L capacity is great. Room for tools on the trail.
So far I've really enjoyed it. Used it for a Hare scramble this weekend and I used up the entire 3L capacity! I never thought I'd need all of it. The bite piece is nice, and the large storage area in front of the water pack is great for longer tools, and a smaller zipped pouch on the outside pack for smaller things like spark plugs , snacks etc. It even has a "tethered" center section that looks to allow you to put a tube or something else that you can wedge in there and tighten down. Overall great pack, very happy I bought this one.
