Triathlon swim caps are typically made of silicone for durability and reduced drag in the water, while neoprene swim caps help keep you warmer in open water. Open water swim caps for tri often come in bright colours to enhance visibility for safety during open-water swims. Find normal swimming hats right through to thermal swim caps in our triathlon swim accessory range at Sigma Sports.
