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.

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 Nice fabric, style and color Nice rash guard as it has backing that holds it in place. I own two of these in different sizes. I wear my XS for water sports and my XXS for swimming laps. I have small hips so the XS still did not stay in place on me. While the XXS is tight when I put it on it is great for swimming and stays in place.

Rated 5 out of 5 by from Selections for everyone I love the color selection and fit on their rash guards. I get compliments whenever I wear one traveling. They are light enough to wear over a tank top or fitted tee and compact enough to carry in a purse or tote. I've worn through Disney without additional sunblock and works like a charm. Plus they are quick drying. My favorite purchase every year.

Rated 4 out of 5 by from Fabric and sizing This is the second L/S swim shirt I ordered from Coolibar. The fit ran slightly smaller in body and arm than the White I previously purchased. I would prefer if the fabric was lighter in weight and smooth texture so that it would dry quicker. It does prevent sunburn!

Rated 4 out of 5 by from Really liked the high tide shirt I bought this for my sister. She loved the great color and comfort. Could be a little short if you are over 5'7", and want coverage for your tummy, but otherwise a great purchase.

Rated 5 out of 5 by from Athletic Trainer This shirt is super comfortable and allows your body to breath with movement! I used it hiking, canoeing, biking and zip lining in New Zealand!! Love Coolibar and their clothing! Top notch to other I have tried!!!

Rated 5 out of 5 by from Awesome Product I purchased this shirt and some leggings for a recent trip to Hawaii. I couldn't have been happier. Hawaii bans any sunscreens that are not reef-safe, and they particularly recommended wearing sunscreen clothing and skipping the sunscreen lotions altogether. I so proud that I was wearing my Coolibar! I am also allergic to the sun and didn't get any sun rash from snorkeling! And it's fits beautifully and is super comfortable. While I won't be snorkeling in Minnesota, I'm excited to wear my Coolibar clothing for biking. And I'm SO GLAD you are right in my backyard in Minnesota :)

Rated 5 out of 5 by from My first but NOT my last! I got this as a Christmas gift after being diagnosed with melanoma in October. I got the poppy red and although red is definitely not my color (reddish blonde hair and light skinned,) this color looks great on me! I'm 5' 2" and 135 pounds with a large chest and the small is perfect. I've been in Mexico for the past week and this shirt has been the best sun protection ever. I also wore this shirt hiking in Arizona last month and it performed exactly how I was hoping. It's flattering to my figure but not skin-tight, even soaking wet. I'm ordering another one asap!

Rated 5 out of 5 by from Nice looking and practical I bought this shirt for swimming and snorkeling in the Carribbean. It was so much more practical than trying to cover my skin with sunscreen! I never got burned wearing to. The size was slightly large so if you are looking for a tight fit then one size down might work. I also wore it at times under my wetsuit scuba diving. It made the wetsuit easier to slip (and pull) on and provided a little warmth. I got compliments on how colorful I looked. It also dried really fast. I had one in pink and one in black and white print. The cost of these shirts is made by the savings in sunscreen products. I highly recommend this product

Rated 5 out of 5 by from Great Fit I. Love the fit. And I love the color. But if it wasn't on sale. I can't afford these clothes. I would never spend this much on a top. But I wanted to try what all the fuss is about.

Rated 2 out of 5 by from Hot and uncomfortable I recently purchased the L/S Hightide swim shirt and am unhappy with my purchase. From reading the reviews I expected to feel cool or at least comfortable while wearing this shirt. Neither was the case. I felt very hot while wearing the shirt. The shirt also felt very uncomfortable when wet. The sleeves were too tight and clung to my skin and the texture of the wet material against my skin was irritating. I had high hopes for this swim shirt, however, I don't know if I can endure wearing it again.
