HydraPak Ultraflask Speed 500ml

Speed up the switchback with the UltraFlask™ Speed 500ml by HydraPak.

Constructed with soft, supple TPU with abrasion-resistant features and RF welded seams for added toughness – bound from the roads to the rocks in lightweight comfort. Walk on air thanks to the bounce-free stability of a vest-pack fitting, and feel the burn in only the right places owing to a flexible flask shoulder to prevent chafing. Jet off on treks thanks to a high flow bite valve for fast refreshment in spurts, with auto-sealing to prevent leakage - so you can continue to run the off-tracks dry. This flask folds with you, shrinking as you drink for minimal water movement and compressing to a flexible pack size. A wide working temperature range means you can bound from sunbaked bitumen to frosted rocks with adequate hydration.

For water that works with you, the HydraPak UltraFlask™ Speed 500ml sends you speeding up the slopes.
