Source Wxp storm valve black hydration system 3 liters

Cleaning and maintenance is not an issue: Water stays fresh and tasty for days and weeks - just fill, drink, refill.

An antibacterial agent permanently embedded in the reservoir's Glass-Like film keeps your water fresh and clean. It has no effect on the contents, is non-leaching and effective for the life of the system.


The inside of SOURCE bladders is super smooth, 2000% smoother than competitors, and almost as smooth as glass. This helps prevent bio-film buildup in the reservoir.


All SOURCE bladders are 100% BPA and Phthalate free and retain the pure taste of liquids without any plastic flavor. Your water stays fresh, odor- and taste-free for days, even weeks.


The original user-friendly and air-tight Widepac Slide Closure opens wide, allows easy filling, ice-insertion, cleaning and drying. Appreciated by millions of SOURCE customers for almost 30 years.
