An all-weather backpack carries you from urban streets to outdoor challenges in a clean design that's ultra-functional and water-repellent.

Mesh straps keep things cool and comfortable, and the sternum strap has a handy emergency whistle. A front stash pocket is just right for plane tickets or other small items you want close at
