Made from brushed Polypropylene these liners are extremely warm, breathable and will quickly wick the moisture generated during sailing away from the body. The hydrophobic nature of Polypropylene also means that they absorb very little water, so in the event of a capsize the liners remain incredibly dry minimising the risk of wind chill. These are a liner and should not be used in load conditions without normal glove protection. In addition to sailing they are perfect beneath cycling and motorbike gloves for the sub-zero winter commute and as an extra layer beneath skiing and snowboarding gloves. The liners are a combination of Spandex (10%) and Polypropylene (90%).  New Size Measurement X-Small/Small 20/21cm Medium/Large 22/23cm X-Large/2X-Large 24/25cm
