Being a lifelong user of polyolefin rash guards, I seemed to run into an increasingly difficult time finding short sleeve polyolefin rash guards. Frustrating. Normal rash guards suck big time because they go limp when wet, stretch and feel like a glinging wet teeshirt.... cool on women in contests, not to cool for keeping the wind at bey to preserve body warmth. I looked for an alternative to the lack of availability and expense of short sleeve polyolefin rash guards. Decided to try KoreDry. Excellent product. Not as good as polypro, but a real close approximate at about 1/3 the cost.
Not sponsored or gifted by KoreDry. Just impressed with their product. If you are looking for a longer lasting, much improved rash guard, KoreDry is a good one.
