Enduring product
Many years ago I bought myself a long sleeve radiator rash shirt from my local surf shop to keep warm in the water. My daughter occasionally borrowed it as well. The ribbed stretchy material around the neck and sleeves eventually lost its shape and I just cut it off as it wasn't essential nor needed for structure. It continues to work very well for me. My niece recently has taken up triathlon so I’ve just purchased one for her for Christmas, and a spare one for me. It is stretchy, with a 0.5mm silver coloured neoprene lining. It keeps me warm so I can still swim laps at the ocean pool when it’s 18 degrees pool temperature. I love that it is of good quality, and does the job of keeping me warm. Also I had to change my size, I’m a women’s size 8, my old rash had size S but I thought seeing as I bought it so long ago, they’ve changed the women’s size from S/M/L to 8/10//12. I purchased a women’s 8 for me and it was too tight. Bob from Radiator sent me a mens S, as well as ladies size 10. The mens small fitted me better than ladies 10. He also sent returned parcel bag, too easy! 100% recommend the rashie top and the company.

So good
Bought this to wear under my full length wetsuit for a snorkelling trip to the Abrolhos. The water was cold, everyone else froze, I was toasty! I could enjoy the phenomenal coral and linger without the cold driving me out which is usually what happens. I can highly recommend this rashie. Lots of people on the trip went off to buy one themselves, they were very envious :)

Long sleeve top
Bought size 14 as reviews said sized small. Quite firm to get on but when wet loosens up too much. Maybe should have got a 12 and struggled more to get in. Rubbed around arms when doing a longish swim but fixed that with body glide. Good for sun protection and to keep warm on a longer swim. I’m getting used to it.
