So...have bit the bullet and ordered a 2mm short-arm steamer from NeedEssentials to stay a bit more toasty through winter in SE QLD. May be an odd question, but when I used to prone-surf many many years ago, it was the done thing to wear a rashie under the wettie. Having not squeezed into full-body rubber for 20+ years, is it still something that needs a rashie under it or have wetties improved and no longer need the extra layer to prevent chafing under the arms / around the neck? Bit of a yeast-filled kooky question, I know...
