Warm core or not, some water is so bitterly cold, (or some swims so long), a bit of extra insulation is essential.
The Outdoor Swimming Gloves use 3mm thick high-grade neoprene to keep your hands working in really-flipping-cold water. This neoprene is thick enough to retain vital extra body heat, yet flexible enough to not restrict your strokes.
The neoprene swimming gloves use blind-stitched seams so you don’t get any lumpy bits sticking into your fingers and a hexagonal patterned grip on the palm for clambering on and off jetties — or grabbing your flask of hot chocolate the minute you get out!
