Using state-of-the-art lamination technology, MicroGuard MP® Microporous 18" Sleeves combine a soft, non-woven fabric with a microporous film. A tear-resistant liquid and particulate barrier helps safeguard from blood penetration, various industrial chemicals, along with dust, dirt, and grime. This breathable fabric allows moisture to escape, so you’re more cool and comfortable even as you sweat. The generous 18" length helps cover more of your arms to decrease the risk of exposing skin or underlying clothing to workplace contaminants. Better yet, secure elastic closures on both ends help keep sleeves in place even with repetitive movements. This allows you to stay on task without having to continually readjust your sleeves throughout your work day.
