The patented Source Durabag protection gives the drinking system maximum resistance and also improves insulation, cooling the water for longer periods of time. The reinforced Durabag drinking system is extra flat and fits in any backpack. Thanks to the robust Durabag protective cover (U.S Patent No. 6,247,619 B1) with fastening loops and carrying handle, the reservoir can also be attached outside the backpack. The Durabag is equipped with all the advantages of the Source drinking systems.
Source's co-extruded PE film encloses the liquid without giving it any plastic taste. Of course, the Source Taste-Free film is free of BPA.
Thanks to the Grunge-Guard technology, the surface of the bladder inhibits the growth of bacteria efficiently, effectively and throughout its life. The technology is based on antibacterial materials, so-called anti-microbial agents with FDA approval and EPA registration.
The drinking system is practically self-cleaning thanks to the Source Glass-Like film. The surface of the Source drinking system is significantly smoother than a conventional PU film. This makes the surface almost as smooth as glass. The smooth surface prevents bacteria from settling and biofilm from forming.
Easy Care & Low Maintenance
The advantages of Glass-Like technology combined with Grunge-Guard technology represent a new generation of drinking systems where cleaning is no longer a problem. Simply refill with water and drink again and again. The water stays fresh for days.
