The Alpinismo 55 is so versatile. This 3 lbs. 5 Oz single compartment backpack is made for the multi use trekker. It has daisy chains to attach gear to and an outside envelop for ropes or crampons. Is the 55 liter capacity too much for this trip. The side compression straps wrap around the front to the opposite side of the pack so you can minimize your gear load and still keep everything securely in place.
