The simple design delivers on form and function without any gimmicks. Designed to slip into the shoulder pockets of trail-running vests and backs, the Soft Flask is also at home in the pocket of your cycling jersey.
You can stash it in your running vest, belt pouch, a side pouch on your pack or rucksack. These lightweight, collapsible flask features the classic one-piece silicone bite valve for rapid hydration on race day. Once it’s empty, it folds down small enough to fit in your pocket.
The Black Diamond® 500ml Soft Flask is manufactured by world leading hydration company Hydrapak™.
