• Riders looking for maximum stretch and warmth in a high-end wetsuit.

Which size to choose

Official ION chart. If you are between two sizes, choose the one that best fits your chest and weight: the wetsuit should fit snugly, with no air or water pockets, but still let you breathe comfortably. Check the selector for the sizes available in store. More details in our ION wetsuit size chart.

Frequently asked questions

What does 4/3 mean?

It is the neoprene thickness in millimetres: 4 mm on the torso, where retaining heat matters most, and 3 mm on the arms and legs, so you can move more freely.

What water temperature is it designed for?

ION rates it for cool water, from 10 to 18 °C. How it feels also depends on the wind, how long you spend in the water and how much you feel the cold.

What is the advantage of a back zip?

It is the most convenient system for putting on and taking off the wetsuit: the back entry is wide and simple.
