Asterisk Adult Banded Undersleeves are the genuine OEM knee brace undersleeves designed to be worn between skin and Asterisk knee braces. Wearing undersleeves is essential for all-day comfort with knee braces — they prevent skin irritation and abrasion from direct frame contact, wick moisture away from the leg during intense riding, and help maintain correct brace positioning throughout a session.
The Banded design incorporates grip-banding at the top and bottom to keep the sleeve in position without rolling, bunching, or sliding during riding. This is particularly important during extended motos where repeated leg movement can cause standard sleeves to migrate. The compression fit also provides mild additional support to the knee joint.
Compatibility: Designed for all Asterisk adult knee braces including Carbon Cell 1, Carbon Cell Pro, and Ultra Cell 4.1. One size fits most adult riders.

Asterisk Technologies manufactures motocross knee braces designed for competitive off-road riding. The Cell and Ultra Cell series feature a polycentric hinged design that mirrors the natural flexion arc of the knee joint and includes an anterior tibial restraint system to prevent hyperextension under impact.
Asterisk braces are CE Level 1 certified and designed to be worn directly over base layer or under riding pants without requiring additional strapping systems. The polycentric hinge allows full range of motion in the riding position while the restraint geometry limits the joint angles associated with ACL and PCL loading under crash conditions. Sizing is based on knee circumference for correct hinge axis alignment.
