2L Reservoir 2.0

(4 customer reviews)


The 2L Reservoir 2.0 is made from an FDA approved BPA free Polyurethane material. This material allows the reservoir to be flexible and puncture resistant. The UltraRed™ hose connects/disconnects quickly and features a high flow bite valve. The top slider allows the bladder to filled easier and hold more water. For cleaning and drying, the top slider also allows the reservoir to be turned inside out. RF welds mold the polyurethane together as if it were one piece to prevent any leaks.

    The two liter reservoir is a well constructed item. They have thought of everything . The hose connection to the bladder is just one click and done, the slide bar at the top goes on in only one direction and is tethered so can’t lose it, the bag will turn inside out to keep from getting nasty in between usage, although that’s not really necessary as hanging it upside down with the slide bar inserted in the opening does the trick. All components are top quality and should offer years of service! If any problems should arise their customer service is superb to which I can attest !

    Fantastic reservoir. I have three that I stash along my long run routes. Very well constructed, able to disconnect from the empty reservoir and snap into the next one quickly during the run without a drip. Well made bite valve, easy to clean. I can also vouch for outstanding Ultraspire service.

    Just a well made product. They really did think of everything. The plug and play hose connection is great, the bite valve works perfectly, and the fact that you can turn it inside out to clean it is awesome.
