Hydro Flask Flex Cap The cap is designed for everyday use from the early morning yoga studio to the place where the trail ends and the adventure begins. The strap is crafted to be comfortable so you can carry your Hydro Flask with you all day long. The stainless steel pivot allows the strap to move when you move, leaving the bottle balanced in carry and packable when stowed. We focused on materials that are built to last for any adventure; from strapping to the side of a raft to the quiet opening during your daily meditation practice.
