The Flipbelt is a classic for a reason, and it ranks as one of Iwanicki’s favorite running belts for its no-bounce fit, multiple storage options, and ease of getting your phone in and out. Though belts like this one can be more challenging to get on and off (you have to step in and out of it), Iwanicki says they often last longer and are less likely to bounce or get stretched out than models that include some sort of adjusting mechanism that could break, slide, chafe, or stretch over time. Of course, there’s a downside to belts that aren’t adjustable—if you get the wrong size, you’re out of luck, and some runners may find themselves in between sizes. In my experience, though, the Flipbelt fit perfectly, and was so secure and bounce-free that I forgot it was there. And though it may look small, it has more storage than you’d think—the super stretchy fabric can hold just about anything you could ever need on the run in its multiple pockets.
