What makes SOURCE different from its competitors ?

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.

A well-made, fairly bomb-proof reservoir that has all the features including a removable tube, a large opening for easy cleaning and a mouthpiece cover to keep it clean. It’s not perfect: the plastic clip doesn’t attach so could be lost. But for performance, convenience, reliability and value for money, it’ll take some beating.

As the name suggests, the Source Widepac bladder has a wide top opening that makes filling, cleaning and drying the reservoir as simple as it needs to be. This opening is closed with a chunky ‘fold and slide’ lock that is secure, reliable and convenient, even when wearing gloves. The hose attachment is of the quick-release valve type, which enables it to be removed without losing fluid from the bladder – a feature that makes refilling on the hill a much more straightforward process and also aids cleaning. At the other end of the hose is a chunky bite valve with a mouthpiece cover. The flow of water can be turned on and off by simply twisting the bite valve, and the movement is solid and definite. It’s difficult to find fault with the Widepac; a hose clip and a retaining cord for the slide-lock (neither of which is included) would be nice, but neither is essential. Water from the Widepac is completely tastefree and all its features come at a good price.

With all the features you’d expect from a top-quality bladder at a price that makes it great value too, the Widepac is an excellent choice for walkers.
