Following the previous reviews I decided to look for the unisex size chart of aeroskin. According to my weight (144 lbs) and height (5.25) medium size should fit me, it did not. The sleeves and shoulders were way too big. I have a roxy rash guard that is 2 size bigger than my size and it rolls up and makes swimming very uncomfortable. I wanted to replace it with this, but this will give me the same problem. I don't think a smaller size would fit better since it was quite tight in the chest area. It is not a good idea to buy unisex rash guards, they simply won't fit.
