great pack. i ice climbed with it all winter and couldn't be happier. the tool carry system is great as is the crampon pocket. one slight drawback is no access zipper to get into the pack; you have to go through the top. this pack is going to kill it when im cragging this summer too. since i am a broke student, i will be using this pack for pretty much everything else i can think of including plain old backpacking.
bottom line is if you are like me and cannot afford to own a quiver of packs, i think the variant will get it done for any outdoor pursuit you can think of. it is that versatile and comfortable.
