Fit is true to size, feels great!
This is the second color I have purchased in this style - LOVE it! Fits well and is very versatile in how it can be worn both short and longer as needed. Great material, very attractive and fantastic sun protection! 5'9", 126lbs purchased a M.
This was a rash-guard I bought for a beach trip. I wanted a shirt that had something more form-fitted because I don't have much of a waist. I ordered the M and it actually was too long in the arms and wide at the shoulders. Switched to a S and am happy. Looks good and is comfortable. Very durable too.
