This backpack is large enough to fit what you need for a day on the trails, yet low-profile enough not to get in your way. Three liters of water are readily available thanks to the hydration sleeve and reservoir. You'll get a customized fit with the Shift RS Suspension system, ensuring a comfortable riding position. When you need to shed your extra layers, you can tuck them away securely in the stretchy front pocket. Pack your tools, your water, your snacks, and anything else you might need in the Gregory Drift 10L Backpack.
