The Gregory Drift 10L Backpack provides enough space for cranking out miles on the trail, yet low-profile enough to comfortably ride the lift on epic downhill days. The dedicated hydration sleeve comes with Gregory's 3D Hydro Reservoir for a comfortable fit that keeps 3 liters of water just a bite-valve away. The load is lifted by the Shift RS Suspension system which adjusts for a customized fit--moving up or down your back for a comfortable riding position. The Drift also features the Matrix Ventilation System which combines a foam matrix in the back panel with mesh construction, ensuring that your back and shoulders receive plenty of airflow. The low volume is complemented by a stretchy front pocket which expands your storage options to include space for an extra layer or rain jacket. Bike-specific organization system includes dedicated storage for pumps, tools, energy bars, and everything else you could need.
