Description
The HydraPak UltraFlask Speed 500 ml delivers the perfect balance of slim profile and structural stability. Its wider bottle base and 3D-welded bottom construction provide greater stability and strength compared to typical soft flasks. At the same time, the flexible, soft-touch material allows the UltraFlask Speed to fit neatly into running pack or vest pockets, while the signature SpeedFill™ cap makes refilling fast and convenient.
