Sun Fact

Research suggests that nearly 90% of melanomas are caused by exposure to ultraviolet (UV) radiation, either from natural or artificial sources.

Aqua Classic™ Fabric

This is where it all started! We set out to develop a superior UPF 50+ swim fabric that didn’t feel heavy or rubbery like scuba rash guards. The result is a technically elegant, sun-safe swim fabric that is chlorine and saltwater resistant with a modest 4-way stretch. It’s silky smooth on the inside with a figure-flattering matte surface on the exterior. Customers love our Aqua Classic because it’s lightweight, quick dry and comfortable.

100% Polyester

Rated 3 out of 5 by from Feedback It is not very long in the torso, otherwise a nice fit

Rated 5 out of 5 by from I like it a lot! I purchased this shirt for snorkeling in Hawaii. It fits well and is very comfortable both in and out of the water. It provided me with excellent sun protection. While snorkeling it floated up a bit so I managed that by tucking it in to my swim trunks. The surprising result of that was a small amount of added upper body warmth. I am 5'9" tall and 170 pounds. The large fit me perfectly.

Rated 5 out of 5 by from Feels great, looks great, protects like a champ Bought this for a kayaking beer crawl and was exactly what I needed. Protection from the sun while being out in the sun all day. The fabric feels great against my skin. Everyone is always giving me compliments on my Coolibar products.

Rated 3 out of 5 by from Good sun protection/bad drying Wish it had dried quicker after swimming. Great sun protection though so still worth it!

Rated 5 out of 5 by from Terrific sun short I have worn it several time during my daily walks in the sun . It gives great protection and is very cool. The shirt launders nicely. Will buy again. Which there were more colors to select from, particularly say, a bright lime green.

Rated 3 out of 5 by from Swim shirt feels good but neck isn't smooth Feel of short sleeve swim shirt and sleeve length is good. Neck doesn't sit smoothly due to stitching. It fits in a square. Fit is loose for a thin build so go down in size.

Rated 5 out of 5 by from Great Shirts I now own 6 of these shirts in every color. Being in Florida, I need protection from the sun. They do a great job and well worth the money.

Rated 4 out of 5 by from Great sun protection shirt Great for blocking sun, looks good, dries quickly, but runs very big. Had to return and order a smaller size. Wish Coolibar paid for return shipping.

Rated 3 out of 5 by from Not the same color as online The product quality looked roughly on par with previous purchases (I've bought a half-dozen previous items), but maybe just a notch lower. The color, though, just wasn't right. I ordered red and they sent something kind of red, but not really red. And not the same as pictured online. Not a huge deal, but kind of feel like I shouldn't have to pay return shipping for something not my fault.

Rated 5 out of 5 by from Boys swim shirt Bought a swim shirt for my son because he had grown out if his old Coolinar swim shirt. These shirts are fantastic and I never have to worry about his arms, shoulders or back burning.

Rated 5 out of 5 by from Awesome beachwear I bought two shirts prior to my Hawaii trip and I'm very happy I did. These shirts provided perfect protection from Hawaii's very strong UV rays. They dried quickly and I liked that the collars were higher to help protect the neck, which other companies don't provide. Definitely would recommend these shirts to anyone looking to have great sun protection and a perfect shirt for the beach.

Rated 4 out of 5 by from Great, except 'Red' is not actually red The swim shirt is great. Coolibar makes very high quality products, but the red color is not red, it's a salmon/pink color. This was disappointing. The size was a little too large also. We exchanged it for another size and color.

Rated 5 out of 5 by from Fits perfectly! Bought it for use on the hot, sunny south Florida beaches. It works very effectively, looks great and fits very nicely!

Rated 5 out of 5 by from No Worry in the SUN! I recently purchased a Men's Swim Shirt which I wore for the first time this March in Tulum, Mexico. I have to be very careful in any sun environment because of serious skin cancer issues. I couldn't believe how effective the shirt was protecting me from those lovely tropical rays. Once out of the water and sitting under a palapa, the shirt lost any wet feeling in minutes. I leaned against a wooden table while having lunch and got the front dirty. A dip in the ocean got rid of most of the dirt and a quick wash in the shower got rid of the remainder. We do a lot of kayaking and boating on Long Island Sound and this shirt will be perfect. Guess what will be on the top of my Father's Day list!

Rated 5 out of 5 by from Great fit, looks great and wonderful protection! I bought one for both my husband and father and law for a recent trip to the beach and they both looked so nice in this. Bought a gray and a navy one and the darker colors really were slimming. Both guys wore them the entire time...(these are men who normally when you buy them something it never gets used)... :)

Rated 5 out of 5 by from Great Shirts for Water Sports When you get the 40% off special, the cost of the shirt makes it a great deal. Normal price is a little on the High Side

Rated 5 out of 5 by from Satisfaction Once Again All the products that I've purchased over the past year have exceeded my expectations. Now that summer is over I will be looking at more casual clothing styles offered by Coolibar.
