Stayed out and lots of room in there!
"This is a great belt I used for Hyrox. I’ve used other belts for running but they tend to flip around. This has a nice thick strap and grip beads on the back so it doesn’t budge. Also didn’t realize how large the pack itself is! It can be small for a gel but also expands for a phone. Only used it for a gel but nice to know there’s that option if I want to try it for a longer run."
