The Hydrapak SkyFlask Speed 0.5 L soft flask delivers practical, comfortable hydration thanks to its compressible format — ideal for trail running and outdoor activities. Insulated with IsoBound™ technology, it keeps drinks cold for longer while providing a stable, ergonomic grip.
The Hydrapak SkyFlask Speed 0.5 L soft flask is designed for activities where hydration needs to stay simple, fast and comfortable. Its lightweight, flexible format makes it an ideal companion for trail running, fast hiking, running or bikepacking. The compressible design allows the flask to contract as liquid is consumed, minimising water movement and improving in-hand comfort.
This insulated version incorporates IsoBound™ technology, designed to keep drinks at an ideal temperature for longer than a standard bottle. The double-wall construction with cellular foam forms an effective barrier against heat transfer, keeping water cooler for longer — even during physical effort.
The SkyFlask Speed 0.5 L also stands out for its ergonomic grip. The innovative thumb loop lets you hold the flask without constantly squeezing it, reducing fatigue during a run. The neoprene padding provides a soft, comfortable feel, while the adjustable Velcro strap fits different hand sizes for a secure hold.
Ambidextrous, it can be used in either the left or right hand, with or without the thumb loop depending on preference. The SpeedFill cap enables fast filling and provides a reliable seal to prevent leaks. Easy to maintain, the flask and cap are dishwasher safe, while the removable strap can simply be hand-washed.
