I swim 3-5 days a week and depending on the weather the pool can be pretty cold, below 72.  This shirt is perfect, keeps me comfortable while swimming.  I also teach water aerobics and when the wind blows in the winter it can get chilly and this works for that as well.

Fits well and looks good. Haven't had it in the water yet, but I can tell it's going to become a favorite

I bought the O'neill Rashguard for sun protection and I love it! I have a history of skin cancer and was advised by my physician to wear long sleeve swim wear protection. After looking at many sports and swim apparel shops, without success, I decided to surf the web and found it. I wear it every time we go on the water (for basic water skiing, tubing, etc.), and for hanging out with friends on and around the water. Many of my friends ask me if I get too hot wearing it and I can honestly say I haven't. The thinner neoprene material lets it breathe and it feels great. My thoughts on the price had me debating this purchase. Now, I am very happy I followed my instincts and went through with the purchase.
I do wish there were coupons available and there were more colors to choose from. I may have been able to purchase more than just the one. Overall though, I am satisfied with this item and with Swim Outlet. Thank you!
