The belt was very comfortable to wear. It fit securely around my waist, did not bounce, and I could barely tell that I was wearing anything! I also like the bottle add-on. It was convenient to be able to wear the bottle on my front while it was full, and then I could slide it to my back when it was empty. The 6 ounce bottle was perfect for a 5k run or less, but you would want something more for a longer run.
Overall, I am very impressed with the new Fitletic belt. I like that it fits my phone and is very comfortable. I also like the option to take the water bottle on and off, as needed, and that it is easy to move around.
Have you tried any Fitletic running belts? How do you like them?
