28mm Flip Cap

This replacement cap features an easy to drink from silicone nozzle which auto-seals after each sip and includes a flip cap cover to keep away outside elements. Fits all current HydraPak products with a 28mm opening including the Stow 500ml and 1L bottles, and SoftFlask 150ml.

Note that caps only fit on the 28mm threads of 2020 models or newer.
