HydraPak Polar Sport Pulse 700ml bottle – HydraPak insulated soft flask, 700 ml, Black

The HydraPak Polar Sport Pulse 700ml is an insulated soft flask designed for outdoor and athletic use. With a 700 ml capacity and a collapsible construction, this black sports bottle combines lightweight portability with thermal insulation to help maintain beverage temperature during runs, rides, gym sessions, and day hikes. Its soft, flexible body allows the bottle to be packed or stowed easily when empty, while the insulated jacket reduces heat transfer and helps keep cold drinks cooler for longer.

Advantages

The insulated soft flask delivers a balance of low weight and temperature retention without the rigidity of a hard bottle. Its collapsible design minimizes bulk as fluid is consumed, and the soft mouthpiece and secure cap provide on-the-go access with controlled flow. The black exterior offers a neutral look that resists visible staining and complements athletic gear. Materials are chosen for flexible performance and easy storage.

Suitable for

• Road running, trail running and interval training

How to use

Usage recommendations

For best thermal performance, pre-chill the flask with cold water before filling with your drink. Rinse thoroughly after use and hang to dry. Inspect the cap and mouthpiece periodically and replace the flask if you notice damage to the seals or fabric layer.
