One of our largest and most popular daypacks, the Adventurer is built to last for years, and has multiple features that keep it efficient and comfortable, even when carrying heavier loads. Padded air mesh on the back panel and contoured shoulder straps provide welcome cushion. Sternum strap, stowable waist belt and dual compression straps stabilze the load and distribute the weight evenly. Multiple pockets, including zip access to a laptop sleeve and accessory pocket are ideal when traveling through airport security.  Hydration compatable.
