Our Maintenance socks have a spunbond outer skin with a recycled hydrophilic absorbent filling, with added SAP (super Absorbent Polymer). Our socks offer fast wicking and excellent retention via the SAP. Our absorbent core is housed within the spunbond outer skin and held together by clips each end, offering the perfect solution to containing small incidental spills. Where liquids need to be contained and absorbed, your best choice is one or more of our absorbent socks, this offers a barrier to stop any spills spreading. LU75-2001
