The BioSkin Under Skin is a thin, lightweight undersleeve designed to provide extra compression and prevent skin irritations while wearing a rigid brace. Unlike softer spandex/lycra models that stretch out and break down quickly, this product is manufactured out of a thin tri-laminate material that maintains its stretch characteristics for optimal compression compared to other conventional under sleeve designs. Because of its compressive nature, it controls swelling and aids in pain relief more so than other softer models available. It's lightweight and allows perspiration to escape instead of being trapped underneath. The BioSkin Under Skin is 20" in length and can be hand washed for proper care. Proudly made in the USA for exceptional quality.

Sizing chart

For the best fit, keep in mind that BioSkin makes their products specifically for very fit, toned individuals that are serious athletes.
The Under Skin is meant to have a snug fit, but if you are on the absolute border of two sizes, and aren't extremely toned, please choose the larger of the two sizes.

While standing with your foot flat on the floor, measure the circumference around both the mid-line of the patella and the thigh 7" above for the correct size.

Good Fit
I wear a knee brace because of an injury I got in soccer. This sleeve is really great: it protects me from my brace which typically irritated my skin when I sweated. Thanks to this sleeve I don't have to worry about this anymore!

So pleased!
I hated how my ACL brace constantly slid down my leg. The brace was well made but just couldn't stay in the same spot. I looked into purchasing an under sleeve and this one seemed like it would do the job of keeping my brace in one place. I used the BioSkin as soon as I received it & I was excited with how well it kept my brace from moving around. Will highly recommend to others...

I've got sensitive skin and was happy to find a compression sleeve that protects my leg from the ACL brace I wear, yet doesn't make my skin breakout in dermatitis. This "underskin" seems to work well and not make me too hot either.
