HydraPak insulated soft flask Polar Sport Pulse 700 ml, White

The HydraPak insulated soft flask Polar Sport Pulse 700 ml in White is a flexible, packable beverage carrier designed for active use. Its insulated body helps reduce temperature change in liquids, while the soft-touch exterior provides a comfortable grip. The lightweight cap and valve system enable spill-resistant drinking and easy flow control, and the collapsible design reduces bulk as liquid is consumed.

Advantages

The insulated walls slow heat transfer to maintain drink temperature longer than a non-insulated soft flask. The soft, flexible construction makes the flask packable and space-efficient when empty, and the soft-touch exterior improves grip in wet or sweaty conditions. The lightweight cap and bite valve are designed for straightforward one-handed use and offer a balance of flow and spill resistance. The 700 ml capacity suits medium-length activities without adding excessive weight.

Suitable for

• Running and trail running
• Cycling and mountain biking
• Day hiking and fastpacking
• Travel and outdoor training

Key specifications

• Capacity: 700 ml
• Insulated body to reduce temperature change
• Soft, flexible, packable construction
• Soft-touch exterior for improved grip
• Lightweight screw cap with bite valve for spill-resistant drinking
• Collapsible as liquid is consumed to save space

How to use

Fill the flask with the desired beverage and secure the cap. For drinking, use the bite valve and control flow with gentle pressure; the valve provides spill resistance when released. After use, empty remaining liquid and allow the flask to dry fully before storing to avoid odors. When empty, roll or fold the flask to minimize packing volume.

Usage recommendations

Rinse the flask with warm water after each use and allow it to air dry with the cap removed. Avoid hot liquids above the manufacturer's recommended temperature range and do not freeze while full. Inspect the valve and cap periodically for wear and replace components if they no longer seal properly.
