SOURCE Hydration Technology

Widepac Closure (U.S Patent No. 7,648,276,B2) - The original user-friendly Widepac™ Slide Closure opens wide, allows easy filling, cleaning, draining, and ice insertion. Airtight seal. Most SOURCE Hydration Systems and Hydration Packs feature reservoirs with our signature Widepac Closure.

Taste-Free™ System - Our co-extruded PE film retains the pure taste with absolutely no plastic flavor, also over time. (BPA and Phthalate free.)

GrungeGuard™ Technology - Our GrungeGuard™-Technology inhibits bacteria growth on the reservoir and drinking tube for the life of the system. Technology utilizes FDA-approved and EPA-registered anti-microbial agent. 

Glass-Like™ Technology - SOURCE's Glass-Like™ Film is 2000% smoother than standard TPU films, with virtually no difference from glass itself. This multi-layer Polyethylene film, manufactured in accordance with SOURCE's Glass-Like™ technology, prevents bio-film build up, making the system virtually self-cleaning.

Easy Care & Low Maintenance - Glass-Like™ technology combined with Grunge-Guard™ technology represents a new generation in hydration systems, in which cleaning is no longer an issue! Simply refill with water and drink again and again without special care. Water will remain fresh for days and even weeks.
