Performance
-
Held where it counts
Muscle Mirroring maps the pressure to the muscles actually doing the work, so you get support where you need it and freedom everywhere else.
-
You will forget the waistband
ComfiBand regulates its own pressure. It holds through the hardest sets without rolling down or digging in.
-
Stretch you never fight
The give is built into the fibre, not cut into the pattern. It moves every direction you do and returns to shape instead of bagging out.
-
Nothing to rub
Seams are bonded, not stitched. No ridge sitting where your leg moves, and no hot spots an hour in.
Apex React XP 5" Muscle Mirroring™ Performance Boxer
Muscle Mirroring is our patented 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 and globally patented, built for athletes who train with intent. The 5" length delivers targeted support and unrestricted movement for high-intensity sessions.
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.
