HydraPak SkyFlask IT Speed 500 ml — collapsible soft water bottle for running

HydraPak SkyFlask IT Speed 500 ml is a lightweight, collapsible soft water bottle designed for runners and fast-paced activities. Constructed from flexible, BPA-free material, the bottle reduces bulk as liquid is consumed and packs down flat when empty. The low-profile cap and clean-flow valve enable quick access to hydration with minimal sloshing and secure closure for road or trail use. Its 500 ml capacity balances enough fluid for short runs and training sessions while keeping overall weight and pack space low.

Advantages

The SkyFlask IT Speed 500 ml offers a minimal, ergonomic shape that fits comfortably in hand, pockets and running vests. The collapsible design eliminates excess movement as volume decreases, improving comfort during high-intensity efforts. The materials are BPA-free and durable for repeated use, and the low-profile cap reduces wind resistance and snagging in active environments. The clean-flow valve delivers controlled liquid flow for fast sips without the need to chew or open complicated mechanisms.

Suitable for

• Road and trail running
• Interval and tempo training sessions
• Race day hydration for short to mid-distance events
• Travel and packable outdoor activities

How to use

Fill the HydraPak SkyFlask IT Speed with water or an appropriate sports drink up to the indicated capacity, then secure the low-profile cap. During activity, squeeze gently to increase flow or sip through the clean-flow valve for controlled hydration. After use, open the cap to rinse and allow to air dry before storing collapsed. Regular cleaning prevents residue from sports drinks; follow manufacturer care guidance for best results.

Usage recommendations

For optimal performance, use plain water or properly diluted electrolyte solutions to reduce stickiness and residue. Rinse the flask promptly after drinks with sugars or additives, and store collapsed in a dry area to preserve material and valve function.
