Perfect Fit

I wish I had bought this sooner. The belt is adjustable and it is designed in a way that it doesn't bounce when I'm running. The pocket is expandable and I can fit my iPhone 11, ID and credit card, keys, and energy gel in there comfortably.

Nathen Insulated Hydration Belt

Really good product. Biggest benefit is that it doesn't bounce around. The belt holds the bottle close without being overly tight. Belt adjusts easily while running.
