The Billabong Furnace Thermal rash vest is made from a thermal polypropelyne with 8oz lycra side and sleeve panels. A thermal rashy is the best way to add some additional warmth under your wetsuit and great on its own with board shorts. They're far more flexible and comfortable than neoprene rash vests and so much warmer. A great way to squeeze another month out of your summer wetsuit and bolster your winter wetsuit when the mercury really takes a dive.
