As one renowned rock climber put it If you plan on climbing alpine style, then the Direttissima is the pack for you. The Direttissima's straightforward design allows you to fill it to the brim with everything you need for base camp without breaking your back. Take off the lid and strip it down for the perfect Alpine assault pack. The Mountain Hardwear Direttissima Backpack is a 52 liter, heavy duty climbing pack for long days in tough conditions or multiday trips. With removable hip belt, frame sheet and lid, the pack can be compressed to the body for small loads. Compression straps tuck away for a clean look and superdurable HardWear tarp slides over rocks and sharp edges.
Solid, tough, versitile backback
This backback has a great feel even when loaded to the hilt. Tough exterior is excellent for climbing in and around rocks. Tradeoff is that it is a bit heavier than some - but all in all an excellent and versitile pack.
Tough, simple and nice looking
I just used this pack to climb Pico de Orizaba, I used in the assault form (without the frame and lid), very useful and practical. Strong enough to deal with crampons and ice axes, capacity is more than enough for a 3 days adventure. Is a straight forward climbing/mountain pack, not a summer/railroad/europe pack so don't expect fancy stuff.
