New for 2019, engineered with more high performance features and an enhanced design for 20% more flow. High performance athletes need high performance hydration. The Force 2L is ultra-durable and designed for action. The 36 flexible HydraFusion drink tube insulates in hot weather and protects in tough conditions. The high-flow bite valve not only has a dust cover, but it self-seals and features a twist on/off bar to prevent leaks. Ready when you are.
