The HydraPak Skyflask Speed 350ml is a flexible and lightweight bottle. It is compressible and shrinks as you drink, ensuring easy storage when completely empty and reducing water movement.

This bottle also has an adjustable strap to fit any body shape and is ideal for running. The cap has two openings: one in the shape of a teat and another larger one for drinking at a higher rate. The large opening under the cap allows for quick refilling and the addition of ice cubes, as the bottle can withstand freezing and temperatures up to 60°C.
