Hydrapak UltraFlask Speed 500ml - Trail Magazine Review

Posted by Trail Magazine on May 04, 2022

The thing about water bottles is they take up a fair amount of space. Not so the Ultraflask, which is made from a soft, flexible material and can simply be rolled away when empty. It's also incredibly light, weighing just 41g. You can even freeze it, so on really hot days you've got a supply of slowly thawing icy water.

VERDICT

designed for trail runners, and excellent for hillwalkers, this ultralight, flexible bottle saves space and weight.
