Apex React XP 5" Muscle Mirroring™ Performance Boxer
Muscle Mirroring is our patent-pending compression geometry. We map pressure to the muscle groups doing the work, so support lands where the load does rather than squeezing the whole leg evenly.
The Apex React XP 5" Muscle Mirroring™ Performance Boxer is lab-engineered, with patent-pending Muscle Mirroring™ and patented ComfiBand™, built for athletes who train with intent. The 5" length delivers targeted support and unrestricted movement for high-intensity sessions.
Patent-pending Muscle Mirroring™ technology applies muscle-specific compression to key working groups, improving stability, circulation, and recovery efficiency. The pressure-regulating ComfiBand™ waistband provides secure comfort without restriction — even under load.
