As one renowned rock climber put it: If you plan on climbing alpine style, then the Direttissima is the pack for you. The Direttissimas 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 multi-day 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 super-durable HardWear tarp slides over rocks and sharp edges.
