For water sports or any where you wish to stay warm, used in sea kayaks, canoe, waterskiing, sailboarding, any waterborne activity where you need to be warm, especially if getting wet. Made of Polyprop/spandex this is a full fleece (winter) version with a full brushed fleece on the inside, smooth on the outside plus neck zip. The fleece is such that it provides breathability but clings to the skin providing warmth if immersed in the water. these garment are designed to cling fit with a little stretch to provide the warmth needed if immersed. Great for kayaking which was our intended purpose. No longer have kayaks so selling all gear. No rips or tears or stains in great condition, zip works and is an extra benefit for ventilation.measurements:chest pit to pit: 14.5'length: 22.5'
