Description:
The Alpinisto is a 50L pack specifically for climbing. It can be stripped down from it's starting weight of 4lbs. 11oz. to 3lbs. and 11oz. by taking off the waistbelt, framesheet, stay, and bivy pad. It also has a hydration sleeve and port, a crampon patch, tool holsters, a contoured top loader to accomodate a helmet while climbing, as well as gear loops on the side of the pack. Gregory also makes a 35L version that is about a pound lighter.
During the period described in this review, I used the pack five to six days per week cragging and guiding and twice per month on longer trips.
