"Drink smarter and run further! Your Amphipod Hydraform Soft-Tech Luxe 16 ounce Handheld has been reimagined. Its retractable design keeps the flask secure and ""always full"" as you drink, while dual stabilizing loops and a cushioned thermal sleeve feels great between your fingers. The high-flow bite valve and quick-access gel slots have you ready for anything. It's so good it needs its own podium at the finish line."
