Designed on the concept that it's easier to carry heavy loads when the backpack and wearer work as one, the ACT Lite 60+10 SL Backpacking Pack Women's from Deuter incorporates an Aircontact Lite System that relies on the compression and expansion of hydro and thermo-phobic Aircontact foam to provide ventilation and load-carrying comfort. A continuous air channel along the spine allows warm air to escape and permits cool air to funnel between your back and the body of the pack. Unique performance features of the ACT Lite 60+10 SL pack include ice axe/trekking pole loops, top lid attachment rings, and a front elastic cord attachment for lashing gear. Two elastic mesh side pockets allow for transportation of water bottles and a lined internal pocket, built-in tube exit point, and tube clip on the shoulder strap make this Deuter Women's pack hydration compatible. The new ACT Lite series also features a huge stretch-stuff-it pocket, stretchy side pockets, and double lid buckles for added stability. The SL models offer a women's specific fit with specially shaped shoulder straps and hip belts. These best-sellers are now even better!
