How durable is it? Will it last 6 wks on a kid playing outside or an athlete?
Exos is extremely durable and typically will last longer than either plaster or fiberglass. It will not soften or breakdown if wet. It has elastic and shock absorbing properties that make it more resilient to impact than either plaster or fiberglass. Because it can be remolded, and is adjustable, it can serve the patient through the bone or soft tissue healing phase [6-12 weeks] and afterwards may continue to be used intermittently as a brace for support and protection.
