Everyone's Doing It

I hopped right in the shower without even thinking twice. Amazing!

- Mackenzie, Patient, MI

“No itch, no sweat. I forgot I was wearing it.”

- Lynne, Patient, TN

“It didn’t need a saw to be removed and my skin wasn’t all gross or smelly.”

- Angelica, Patient, IL

Infinitely better than a fiberglass cast. So much faster to put on and take off. I don't have to itch, and it dries by itself. I was hesitant at first, but the xrays showed nothing moved. I healed perfectly.

Iris, Patient, IL

10/10. It's easier to use and my patients actually ask for this more often than anything else.
