Copper Fit ICE compression sleeves are infused with a patented micro-encapsulation technology with the cooling sensation of menthol and the energizing properties of CoQ10. The more you move, the more ICE you release. Made with a strong circular knit compression fabric for all-day comfort, the ICE Knee Sleeve is designed to provide more support to help temporarily relieve muscle and joint aches and pains. The seamless anti-chaffing sleeve is breathable, and copper-infused to reduce odors.
