New for 2010, the lightweight Spectro AC 36 SL Backpack - Women's by Deuter is a high-performance carrier for the light and fast, ounce-counting day hikers.

Effectively transferring weight to the padded, contoured hipbelt, the Spectro AC 36 SL stands away from your back as the Aircomfort FlexLite System promotes airflow and helps to keep you cool and collected during active pursuits. Convenient performance features include a large stretch-woven front stuff-it pocket, front-entry two-way zip panel for easy access to gear, ice axe and trekking pole attachments, and stretch-woven side pockets. This women's specific Deuter backpack is also hydration compatible.
