Shed some skin! Only 1.5mm thin but super warm and lightweight even after hours in the water. If you’re really looking for warmth and performance without the bulk this is the real thing.
If you’re not sure you can always just add a Radiator vest for extra warmth when you need it and have a total of only 2mm in thinness. Or try a Short Sleeve 1.5mm steamer with a long sleeve vest - maximum combinations for freedom, warmth and top performance.
