Fabric Details
Aqua Classic™ FabricAqua 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.

Coolibar’s sun protective clothing is designed to be worn in the sun and to provide excellent UV protection. If you have any questions about size, fit or style, talk to one of our Customer Service Representatives at 1-800-926-6509. They'll be happy to help, as well as offer expert advice on coordinating sunscreen hats with your wardrobe.

Match your measurements (in inches) to the chart below. If your measurements fall in between two sizes, you may prefer the larger size.

Due to the range of fabrics and styles, each hat fits slightly different. See individual hat circumferences in the Highlights section of the product page. Our One Size hats are designed to fit most.

HOW TO DETERMINE YOUR HAT SIZE: Measure around your head, from the center of your forehead, keeping tape straight and parallel to the floor. Measure around fullest part.


Measurements XS S/M L/XL
Circumference (inches) 6 - 7 7 - 8 ½ 8 ½ - 10

Measure circumference of hand around fullest part just below the knuckles, excluding thumb. Use right hand if right handed, and left hand if left-handed. Measure hand in inches and refer to the sizing chart for your glove size. Use the larger number to determine your size. People with extra long fingers, or who would like a looser fit should consider ordering a size up.

PLEASE NOTE: The measurements on our size chart are very similar to most major clothing companies. However, we generally allow for a relaxed fit - geared for outdoor activity, travel or a casual outing. Pants, skirts, blouses and polo shirts have extra room for comfort and are not body hugging.

When fitting jackets, cover-ups or any outerwear, our fit model is wearing the appropriate under layers that we would expect you to be wearing. You do not have to "size up" - we have done that for you.


Never try to measure yourself. Seek the help of a companion and use a soft tape measure.

  • Height: Stand in stocking feet, with feet together, back to the wall. Measure from top of head to the floor.
  • Arm: Bend arm to 90 degrees. Place hand on hip. Start at center of back of neck. Measure across the shoulder to the elbow and down to the wrist. Number of inches equals your sleeve length.
  • Bust/Chest: With the arms relaxed down at sides, measure fullest part of bust/chest, keeping tape parallel to floor.
  • Hip: Stand with heels together, keeping tape straight and parallel to the floor. Measure around fullest part.
  • Neck: Measure around base of the neck (the lowest point of the neck). Number of inches equals the neck size.
  • Inseam: Take a pair of pants that fits you well. Measure from the crotch seam to the bottom hem. Number of inches equal inseam length.
  • Rise: Start the tape at the center back waist, run the tape between your legs, pulling comfortably at the crotch and up your natural waist. Total measurement is your rise.
  • Waist: Measure around your waist, against your skin (not over your shirt or pants) at the height you normally wear your pants.
  • Head: Measure around your head, from the center of your forehead, keeping tape straight and parallel to the floor. Measure around fullest part.

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 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 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.

Rated 3 out of 5 by from My nice white swim shirt really Yellowed Up! I've had the shirt for couple of years and love the feel and it is great to swim in. Only down side is my nice nice white shirt turned a dirty yellow after several trips to the beach. I would definitely not recommend white if a you do not want a dirty white looking shirt.

Rated 4 out of 5 by from Haven't worn it yet, but seems perfect Bought for upcoming vacation. Liked everything about the shirt, thus the four stars, but holding back because haven't actually tested it out on the water/beach.

Rated 5 out of 5 by from Really comfortable fit! I am really happy with this shirt. Sizing is exactly like my other regular T-shirts. It feels great in both fresh and salt-water and dries quickly. I love the bright yellow colour as well!

Rated 5 out of 5 by from Excellent protection from sun I have bought these shirts before and am adding more becuase of the great protection they provide. They are durable and hold up well maintaining their protection from the sun. What I also like is that after swiming they dry relatively quick and are very comfortable

Rated 5 out of 5 by from Great product. Great product. My husband had cancerous cells removed from his back several years ago. Ever since then I have purchased this shirt several times for him to use when we go to the pool or at the beach.

Rated 5 out of 5 by from Swim Shirt I bought yet his because last year I found out that I had precancerous areas on my face and body so I looked for clothing with UV protection and I looked around Coolibar had the highest recommendations. I love the product. I wear an extra large and their extra large is perfect fit.

Rated 5 out of 5 by from Great Fit and Feel I bought one for myself and my 2 boys before a week of snorkeling in the Caribbean. This is the first time our backs weren't burnt, and we've tried T-Shirts, UA, etc. before. The fit is true to size, and not so tight as to be uncomfortable. Out of the water they dry quickly; not clammy. The only "oops" we found was when my son accidently squired suntan lotion and it landed in spots on the shirt. It caused permanent "dimples" as if the chemicals in the lotion and shirt reacted. This seems to be cosmetic only. After several washings they still look new.

Rated 5 out of 5 by from Swim shirt Great look, great feel. Went swimming and the shirt felt great in the water and it dried very quickly.
