The UltraFlask Speed is a straw flask that slots into your vest pocket or pack so you can hydrate without having to take it out every time. Perfect for trail running or hiking!
The Hydrapak UltraFlask Speed straw flask is part of the American brand's ultralight range.
Weighing just 60 g, it has a capacity of 600 ml.
The flask consists of three detachable components:
- The body: made from TPU, a flexible and fully collapsible material.
- The cap: it screws onto the body and can be opened when needed. It features a valve if you prefer not to use the straw.
- The straw: it replaces the cap and offers a practical alternative, particularly for ultra-trail runners.
The valve and straw lock automatically. To drink, simply squeeze with your teeth.
As you hydrate, the flask shrinks, minimising water movement inside.
The Hydrapak UltraFlask 600 ml soft flask with straw features:
- A flip cap for easy refilling at aid stations
- Ideal for trail running or hiking
- Resistant to extreme temperatures: sub-zero and up to 60°C (140°F)
Note: the nozzle (42 mm diameter) is compatible with the BeFree filter.
