General: The Source WXP is a powerful 3L hydration reservoir system from a 3-layered coextruded polyethylene construction, including the source-typical taste-free technology, low-maintenance glass-like liner, integrated grunge guard - antimicrobial. Thanks to the built-in glass liner technology with Grunge Guard, bacteria have no chance. This unique antimicrobial system reliably inhibits bacterial growth from the outset. source uses a multi-layered polyethylene film that is 2000% smoother than standard TPU films and consequently prevents a biofilm build-up. Thus is the system self-cleaning. Even after months in use can always be easily refilled water without a need for cleaning. Taste-free technology provides odorless water without any plastic taste.
