Bought this for my marathon vest and it is perfect for my longer runs. I have a waist vest for shorter runs but use the vest for the longer runs and trail runs. I would recommend this reservoir for anyone looking for hydration on longer runs. SEKOTDCOB on May 4th 2016
I really expected this to do one thing... and it did it... It held water while I ran and allowed me to drink water from it, WHILE I RAN!
The bite valve was not as complicated as the bottles, luckily...
Putting water in it and cleaning it after runs is a lot better and easier than that other brand we will not mention by name... but it rhymes with shamelcrack....
At any rate... great product at a great price... The Desert Ape on Apr 17th 2016
Easy to turn inside out to clean and hang to dry. No screw in cap to deal with. Tube goes on and off w/o leaking. A good product. tyler on Oct 27th 2015
Easy to open and close and clean. The spout has no leaking issues and hydration easily flows. Fits perfectly in the AK vest. 70 oz is the perfect size for several hours on the trail. mike on Oct 18th 2015
