Deuter
Deuter Aircontact Ultra 45+5 SL
Best lightweight comfort for multi day backpacking adventures.
Designed for everything from trekking and mountaineering tours to overnights in the front country, this Aircontact Ultra is Deuter's lightest hiking backpack series yet, holding 50L with an additional 5L expansion pack. It is both sleek and spacious while remaining extremely lightweight and comfortable. The Pull-Forward system allows for easy waist belt adjustment to tighten for heavier loads, complemented by an adjustable back length system, mobile, snug-fitting VarFlex ECL hip fins, and an ergonomic lumbar pad for effective load transfer onto the pelvis. The Aircontact back system keeps weight close to the body for effective load transfer via breathable padding made of open-cell, hollow-chamber foam, and an ergonomic aluminum-stay X-frame. An extendable 5-liter spindrift collar provides volume expansion. The SL (Shorter Length) women's fit features a shorter cut, narrower shoulder straps, and conically shaped hip fins for a comfortable and natural fit.
