The Osprey Womens Aura 50 Backpack uses an AirSpeed suspension system to provide serious ventilation that handles even the hottest days. Mesh shoulder straps and a mesh waist-belt add to the cooling, so you can keep hiking in comfort as the sun beats down. Several pockets and a large front flap help you stash all the necessities and keep it all organized. Dont think for a second that Osprey just sized down the mens version. Every inch of this packs suspension has been designed around a womens frame to ensure plush comfort.
