"What Our Gearhead® Experts Are Saying:""The Atom's 15-inch torso length is the detail that makes it work for my petite frame. It sits close without pulling down on my shoulders or riding up on my lower back.""Why We Like ItThe removable padded laptop sleeve fits up to 13-inch laptops and includes a zippered pocket for cords and accessories, so the transition from desk to trail is straightforward. A breathable back panel, hydration pass-through, dual stretch-mesh water bottle pockets, and a bike light clip handle the active side of the day."
