A fueling solution that enables you to carry up to 120g of carbohydrates in your pocket. The bite valve simplifies consumption on the move — on gravel, trails, or mid-race when not wanting to stop. The SpeedFill™ cap makes refills fast by easily popping the cap open. Compatible with the Gel Mix 480 sachet — the opening is designed to fit directly into the top of the flask. Compact enough for a vest pocket, waist belt, or back pocket.
