The largest pack in Gregory's bike-specific line, the Amasa 14L Backpack is designed to help you take on longer rides with little to no support. It has enough space for an extra layer, plenty of water and food, plus the tools, tubes, and other gear you need to ensure you keep rolling. The Shift RS Suspension system lifts the load, and adjusts the hip belt vertically for a customized fit for your torso. Matrix Ventilation Technology uses foam and mesh to lift the pack off of your back, ensuring airflow between you and the back panel.
