SALOMON reservoir Soft Flask 490ml XA filter blue

The SALOMON reservoir Soft Flask 490ml XA filter blue is a 490 ml soft hydration flask with an integrated filter that removes bacteria and protozoa from natural water sources, ideal for longer runs and hikes where refills come from streams or lakes.

Key features

This soft flask shrinks as you drink, which helps reduce water slosh and makes it easier to see how much fluid remains. The integrated filter treats roughly 1,000 liters of water, so you can top up on the move instead of carrying extra weight from the start. A high-flow valve and wide 42 mm cap support quick refills and easy drinking during longer efforts such as ultra-trails or remote hikes.

Materials and construction

The SALOMON Soft Flask XA Filter 490ml uses a flexible body that packs down as it empties for minimal bulk. The construction combines thermoplastic polyurethane for the main body, polyoxymethylene components, and silicone elements to balance durability, flexibility, and a secure seal at the mouth and cap.
