HydraPak UltraFlask IT 500ml

Cool water is just a sip away. An insulated version of our ultra-light UltraFlask 500 ml, the UltraFlask IT 500 ml features our new IsoBound technology. The double-wall construction and open cell foam technology create a barrier – slowing the heat transfer from the user to the hydration.
