Adventure racing, ultralight backpacking, are just a couple prime uses for the Osprey Aura 35 womens backpack. Built specifically for a woman traveling light, this pack is not only lightweight but its exceptionally comfortable too. Ideal for loads in the 30 - 40 pound range, the Osprey Aura 35 backpack owes its comfortable fit to the AirSpeed suspension and ErgoPull hipstraps, all components built specifically to fit women. The primary advantage of the AirSpeed suspension is the uniform back contact provided by a 3D contoured, tensioned backpanel consisting of highly breathable mesh fabric. This offers superb airflow, a real comfort advantage when slogging up a long snowfield in the mid-day sun. The ErgoPull hipstraps transfers the weight evenly throughout the hips, not just across the center portion like so many other hipbelts. The ErgoPull system accomplishes this by drawing tension along the top and bottom of the hipbelt, not through the center, so it distributes pressure evenly over the entire belt. Additionally, womens specific thermoformed and perforated waffle pattern shoulder straps contribute to the ultra-comfortable carry. Along with the comfortable carry, fast access is also a key design feature of the Osprey Aura 35 backpack. Full-length dual zippered panel access to the main compartment allows for quick and easy packing. An internal hydration sleeve, backpanel hydration cavity, and 1-liter bottle compatible, stretch woven side pockets offer multiple on-the-go fluid replenishment options. Also, the hipbelt features zippered mesh pockets for instant access to small necessities and the large stretch woven front sleeve is always available for speedy loading of last minute items. This wide-mouth pocket has an adjustable strap for securing odd shaped contents, small or big. For a larger version of this backpack, be sure to consider the Osprey Aura 50 backpack.
