As the name suggests, the Hydration Moto Race 1.5 HF is lightweight and race-ready. It features a 1.5-liter hydration bladder and a 2-liter cargo space. The lightweight harness system is fully adjustable on the chest and waist to ensure a perfect fit. The AirLine back ventilation ensures optimal airflow, keeping you cool. The hydration tube features a quick-connect system for hands-free hookup and an auto-seal bite valve. An additional 2.0-liter bladder can be added for long rides, while an integrated thermal panel keeps liquids warm when needed. The Hydration Moto Race 1.5 HF is designed to fit with or without a Leatt neck brace.
