The Salomon Hydration Softflask Xa Filter 490ml is a soft flask designed primarily for trail runners and hikers. Specifically, it is a 490ml flask that features a water purification filter integrated into the cap.

• Filtering: The filter removes 99.99% of bacteria from natural water sources.

• Usage: It allows you to fill the flask from a stream, lake, or mountain spring and drink immediately, without waiting for purification tablets to work.

• Design: As you drink, the flask shrinks to take up less space.
