    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.

    Bought mine a few months ago and really liked it. Have only used the bladder about 7 or 8 times with my Momentum 2.0 vest. Saturday I was out for a long run on a hot day and the bladder started leaking. There is a small hole on the seam of the bladder. It put me in a tough position as I had to go a ways without water. Like I said..bladder was great up until that happened.

      Hi Jamie,
      I will reach out to you via email. Your reservoir is still under warranty and that shouldn’t be happening to you. We will make sure to get the issue taken care of.

    Just wanted to follow up to my previous rating on the bladder. Jodi reached out and was able to replace the reservoir very quickly. Great customer service is always appreciated. Thank you for going above and beyond.
