ION’s Select wetsuits are all about ultimate warmth combined with epic stretch and high-quality materials. The materials used to make wetsuits have always had limitations. Some are extremely flexible and others are great in terms of insulation. But it was difficult to find a suit that is extremely warm and super flexible at the same time. Select wetsuits have always belonged to the warmest in the world of wetsuits and now they even offer 30% more stretch just warm as ever, stretchy as never!
