Ideal for extended expeditions like ultra-trails, the SOFT FLASK XA FILTER filters bacteria and protozoa from natural sources so you can drink easily and safely without carrying large amounts of water. This softflask compresses as you drink to limit water sloshing and tell you exactly how much you have left. Diameter of the cap:42 mm.
The filtration system allows you to carry less water, and therefore less burden and fatigue.
This 500ml softflask has a high flow valve for easy drinking and a 42mm wide cap for easy filling.
The filter removes bacteria and protozoa from approximately 1,000 liters of water to allow you to replenish your hydration without risk to your health, even in the most remote places.
August 1985 was the start of a great adventure for Boutique Endurance. Many years have passed, but the passion for running remains firmly anchored in the daily life of the Boutique Endurance.
