Light and fast for the Y axis.

Some packs sit on your back like a pillowcase full of rocks, but the Black Diamond Axis 33 Backpack rides as smoothly as a finely-tuned sportscar, thanks to its ergoActiv suspension that moves with you, eliminating hot spots and allowing for more natural movement so you can cover more ground with less effort. Of course, the Axis is designed with vertical endeavors in mind, but just imagine how many ice or rock pitches you could knock out in a day without your pack pulling you back to earth.

The Axis has a fat-free design, forgoing the unnecessary bells and whistles in favor of ultra-functional features like PickPocket ice tool holders, crampon straps, and a three-point haul system if you end up pulling it up behind you. The SwingArm shoulder straps distribute the load evenly, and the vented, thermo-formed back panel keeps you cool and comfortable when you're pulling through the crux. Incorporate a tuck-away helmet holder, rope strap, and hydration compatibility to keep you well-watered on longer approaches, and you've got the fully-featured but remarkably trim Axis.

Perfect pack for my needs. Really like how it opens up and swallows gear. Comfortable--I'm 6'7" and the L fits pretty well.

Anyone know if this pack is small enough...

Anyone know if this pack is small enough to be used as an airplane carry-on?

Hey Alex,

Most airlines follow the loose rule of 45 liner inches for a carry-on. This pack is about 11 x 7 x 24 so you should likely be fine.

I haven't used this back extensively yet, but wanted to put in a plug from the non-technical crowd. I moved to this from the BD Octane for my go-to backpacking pack. My Octane was 28 liters and I really needed the extra 5 liters for cold weather trips/bear country trips/photo equipment. After tasting the sweetness that is the ergoActive suspension I couldn't go back to a "normal" pack, and I really like zippered packs as opposed to top loading compression style (which you have to move to to get extra space in the BD backpacking lineup - Boost Pack). This fit the bill and if you get creative all those special features for climbing come in very handy for other things. For example, I always hate taking up so much space in my pack for my Bare Boxer, but the hideaway helmet holder is perfect to fasten it to the top of the pack. No extra webbing, and awkward positioning. Just perfect. I don't use crampons, but the crampon holder is perfect for a water bottle or camp chair. Lots of possibilities. Not as light as some backpacking options but I prefer a few extra features and durability to a few less ounces. Obviously mine is the previous model, but I think they are pretty similar for what I just described.
