Customer Reviews

Comments: You guys were totally right. I'm fade up with this too. Their sweet words encourage customers to believe and purchase it. In fact, it's not. I don't believe any of the hydration belts now. Thinking of modifying it the right way. Sponsor athletes will say good about it because they're being sponsored. Wasting money and time trying to adjust to make it fit to our waist. It's pretty annoying.

Comments: I'm disappointed with this one. When I first filled the bottles and tried it on, I liked it. Everything was well balanced and the belt fit snugly. I was really excited because I really liked the way it felt. However, the next day, during my first real world run with the belt, I realized it's major flaw: it won't stay tight. I found myself having to tug the straps tight every few minutes just to keep everything from bouncing around uncomfortably on my hips. Then, every now and then, the straps would bunch and bind up, leading to more frustration. It rides much better when you get down to two bottles, but when all four are filled it loosens up quickly. It's a shame because outside of the tightness issue I like everything else about this belt. The bottles are easy to get in and out of the holsters, and I like the little pack for gels and other items. With the price of this belt, I'm going to do my best to make it work, but I'm bummed to have dropped $40-plus on a belt that I have to mess with constantly during my run. A good hydration belt, for me, is one that is so functional you forget it's there. This one doesn't pass that test by a long shot.

Comments: The worst hydration belt I have had, the front bottles fall out of the holster while running. It was extremely annoying. Won't recommend.
