The 14L is the largest pack in Gregory's Drift Backpack line. This pack helps you take on long, shuttled rides, or equally long, unsupported out-and-backs. The Shift RS Suspension system allows the hip belt to adjust vertically to hit you in a comfortable place as you ride, and stabilizes the load so you can focus on the trail ahead. It also features Matrix Ventilation foam in the back panel to ensure you get plenty of airflow to prevent your back from becoming a swamp. Mesh in the shoulder straps, hip belt, and back panel is designed to wick away perspiration and provide evaporative cooling. Like the rest of the Drift line, the 14L features bike-specific storage for your tools, electronics, snacks, and other gear, plus plenty of space for a layer or rain jacket. The Drift comes with a 3D Hydro Reservoir to ensure you can keep water on-hand, and that it matches your back comfortably.
