Look lively with the Tensor 15, a lightweight multi-purpose day pack suitable for hiking, biking and running, when you want to move quickly but still carry the essentials. The Tensor 15 features the AirContour back system, with a pre-curved back panel that promotes a closer fit and more natural movement. An internal security pocket, zipped top pocket and key clip keep valuables like wallet and phone safe, and for those who like to stay out after dark, reflective graphics and a light loop aid visibility. A hook and loop pole lash, with TipGripper walking pole attachments, and stretch water bottle side pockets make this the ideal pack for short day hikes and longer runs in the mountains.
