The Osprey Sportlite 25 day hiking backpack delivers reliable performance for active hikers and outdoor adventurers who prefer a minimalist technical daypack. This backpack is made of high tenacity recycled material that meets Bluesign sustainable production criteria and features good ventilation at shoulder straps and back panel for superior comfort. Trekking pole loops and blink light attachment slot complete the technical features of that bag. If your adventures require less kit or you want a smaller and minimalist pack, the Sportlite 15 will make a great choice. While this pack may look minimal, it's not so stripped down that it will sacrifice comfort. An AirScape back panel and suspension system moves with you dynamically and keeps your carry stable and ventilated.
