Hydration Belt For Running and Hiking Fits iPhone X and Samsung S8 Plus - Includes 2 Premium BPA Water Bottles

I can rate this 5 stars because I use it for walking not running. It fits snug to your body until you fill the bottles with water. The belt is not thick enough to pull tight so it rests flush against you, but I do not have a flat stomach. I tried to jog with it on just this morning and it was bouncing. Now, I am NOT wearing fabric that the nubs can grip to, I think if I was wearing a cotton shirt or some other not so slick material it may have stayed still, but again it wasn't flat against my body. I wear it turned around so the pouch is in the back so it stays put. The pouch is big enough for my IPhone 6, and fits my keys and lip balm in the front zipper. The water bottles can be kept in place with straps, but even without them they stay put. Sturdy well made product.

I give this two stars because the pouch is rather large and uncomfortable and the bottles never fit securely for me. I used it while running a half-marathon and while running, a bottle fell out of the pouch onto the floor not one, or two, but three times!

Bounces up and down and the straps adjust outward as you run, loosening the belt. Im not exactly petite but a 4/6 and I wear it as tight as it goes. Every couple miles, I re-tighten. That said, price is good and in DC summer, it is literally a life saver.

I really like the comfort non binding feel of the belt but it does slide a bit on me when running. Once I was able to find the best position on my hips it was barely noticeable.I like the pocket so I can carry my electrolyte gel for those long runs.P.S. I will be returning my bottles because one of them leaks at the spigot when running even when it's secured. But I like the betl

Too big. The water bottles hit my arms when I run. Maybe if they were placed closer to the pack if that wasn't so big then it would be better. Otherwise it was really nice. I am a slender woman so if you were larger around the waist it might be perfect.

I received the original design belt and found that the straps were too elastic when I ran so the belt would loosen over the course of the run. I contacted David and he told me that they were working on a new and improved strap. He sent one out to me free of charge and I tried it. It was MUCH better and held up its same tightness throughout a 10 mile run. I have a small waist and keep an iphone 6, key fob and id in my belt along with the two bottles full of water, so the load is fairly heavy and can still handle the up and down motion of a fast run. I am MUCH happier with the new belt and am very impressed by the impeccable customer service!!!

This belt is comfortable but the bottles leak all over my clothes while walking/jogging. Almost a waste to carry bc more water ends up on me.

My 7th hydration belt and least favorite. Too bulky. That said if your headed out on a short hike and need to carry a lot of bars this is good. Terrible for running.
