These are SUPER! I’ve been wearing my pump without the clip — works great in a pocket, by the way, and these solve a lot of the problems. I can put the pump in one of these, pin it to my bra and it doesn’t show as much as it does with the pump. However, I sweat on the pump that way, and the pouch solves that problem.
Will try one of the belted ones when it’s pool time.
