West Marine Three-Season Gloves A full neoprene back provides insulation when the temperature drops. Sailors who need a little extra insulation to keep their fingers functional (you know who you are) will appreciate our Three-Season Gloves. Their 1.5mm-thick neoprene is warm even when wet, yet wont compromise dexterity. Palms have Dura-Grip fabric which improves grip strength, so you dont tire as quickly. The pre-shaped construction fits your natural hand shape, and the extended cuff keeps the water out. Unisex. Mesh/neoprene/Dura Grip fabric. Imported.
