How It Supports
24% Active Copper Ion Thermoregulation
Infused with a real 24% Copper Ion performance fiber, blended precisely with high-elastic nylon and polyester. This specialized weave naturally retains joint warmth, promotes fluid lubrication, and delivers advanced anti-odor properties for extended high-active wear.
360° Ergonomic Joint Alignment Mapping
Utilizes a high-precision 3D woven knitting structure designed to perfectly map the natural 360° curve of your kneecap. It efficiently disperses downward physical pressure and reinforces lateral containment, keeping the joint secure without restricting mobility.
Anti-Migration Slip-Proof Technology
Engineered with high-tensile copper compression fabric integrated with premium non-slip silicone strips. This dual-action anti-migration system entirely eliminates sliding, rolling, or bunching, guaranteeing the sleeve stays firmly locked in position all day long.
Feather-Light Circular Breathing Knit
Features an ultra-thin, premium air-knit profile that delivers a feather-light tactile experience. Optimized with advanced multi-channeled ventilation, it instantly absorbs and evaporates large amounts of moisture through continuous circular breathing.
Invisible Zero-Bulk Layering
Designed with a sleek, low-profile blueprint that seamlessly layers under leggings, jeans, or athletic pants without adding bulk. It delivers consistent muscle containment and tension reduction entirely invisibly, transitioning effortlessly from casual wear to intense gym training.

Size & Fit
Use a soft measuring tape and measure your thigh circumference 5 inches / 12.7 cm above the kneecap. This is the most important measurement for choosing the correct size. Do not choose your size based only on height, weight, or regular pants size.
Choose the smaller size if you prefer a firmer compression feel. Choose the larger size if you prefer more comfort for longer wear.
The brace should feel snug and supportive, not painful or restrictive. If you feel numbness, tingling, or unusual discomfort, remove the sleeve and adjust your size choice.
