The technical Women's Tempest 30 Backpack is a gender specific & perfect for fast day raids into the wilderness, but with enough volume for lightweight weekend challenges. Breathable ventilation is key as the pack sits securely allowing you freedom to roam with your kit stable & safe. The Air Scape mesh covered accordion foam back panel has ridges that fit to the contours of your body, keeping the load close & aiding your stability. Air chimneys run through the foam, letting air circulate around your back to keep you cool. The lumbar to hipbelt body wrap is seamless & shaped to provide comfortable contact with your body & it works with the back panel to reduce the movement of the pack when you are moving fast. The Ergo Pull waistbelt simplifies the adjustments of the hipbelt. With Osprey's Stow-on-the-Go feature, you can quickly & easily attach & release your trekking poles without having to take the pack off your back or stretch uncomfortably & the Power Mesh front stretch pocket will swallow all manner of gear, be it a fleece or a flask.
