HydraPak UltraFlask Speed 500 ml Malibu Blue

HydraPak UltraFlask Speed 500 ml Malibu Blue

The HydraPak UltraFlask Speed 500 ml Malibu Blue is a wide bodied soft flask that sits still in a vest pocket instead of bouncing against your chest. On the Hatta and Wadi Shawka loops, where the trail season runs October to April, two of these cover most of a morning.

Features and Benefits

The SpeedFill cap flips open with one hand and snaps shut leakproof. At a water stop you are filling in seconds rather than fighting a screw thread while your legs stiffen up.

Additionally, the 42 mm opening takes ice cubes and drink powder without a funnel, and it threads onto 42 mm backcountry filters including HydraPak's 42 mm Filter Cap. The high flow bite valve seals itself after every sip, so nothing drips down your front.

Beyond that, the flask collapses as you drink, which keeps the remaining water from moving around and lets the empty pack flat. A 3D welded bottom holds the shape in a pocket, the body is abrasion resistant TPU with welded seams, and it is free of BPA and PVC. Freeze it or fill it up to 60°C (140°F).

Product-Specific Use Cases

Freeze one the night before a Showka loop and it thaws into cold water an hour into the run, which is worth more here than anywhere. The wider body suits the larger front pockets on most vests, and the filter thread turns it into a backcountry option on trips into Musandam and the Omani Hajar.
