There are a lot of things I like about this pack... and only one thing I don't.
I like the 100 ounce bladder capacity, ample storage area and pockets, molded back panel, high waist strap and good build quality.
What this pack is missing is a good pocket for tools storage. Sure it has a pump slot, and a large internal pocket that's great for things like spare tubes and maybe a first aid kit. But there is no pocket for tools, like an allen key and chain tool. I don't want to drop them into the bottom of the pack, and don't want them in the external zip pouch since its too large and potentially can be torn by tools since its mesh. So I am putting them in the MP3 player pouch on the inside of the pack... which is fine, but its not very big and doesn't seal completely. It would have been better if there was one additional internal pocket specifically for smaller metal tools.
Other than that, one of the better packs I've owned.
