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.

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.


Measurements XS S/M L/XL XXL
BICEP (circumference) 7 ¼ 9 ¼ 11 ¼ 13 ¼
WRIST (circumference) 5 ¼ 5 ½ 6 6 ¼
SLEEVE LENGTH 18 20 22 ½ 22 ½

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 Easy to get on and very comfortable in the water Recently purchased because I cannot be in the sun at all and now I can enjoy the pool and not feel like I will get any uv rays.

Rated 1 out of 5 by from Baggy at best I am a big fan on Coolibar so its painful to write a negative review. I bought this Nocona to surf in and it just does not work. I'm 6'4 and 215 lbs so i normally wear an XL or XXL so I ordered and received the XL. It looked and felt fine on land but it ballooned to an XXXL when wet. I wanted to use it for surfing but that won't work. First because it does not have a surf trunk tie like other rash guards that keep the shirt from coming up over your head and drowning you. Thats sad because it would be a simple add costing less than a dime. But the deal killer is that when wet it fits like coffee sack. I would love to return it but its now used.

Rated 5 out of 5 by from Perfect swim shirt I bought this swim shirt for my husband to wear during our recent trip to the Caribbean. He’s 5’10” and 160 lbs. and the size large is a perfect fit! He is difficult to please regarding fit and comfort but he loves the shirt!

Rated 5 out of 5 by from Great rash guard My boys are adult sizes now and still prefer rash guards to loading on sunscreen. They love the zipper crater as it allows them to change more easily. Nothing is as difficult as taking off a wet and sandy rash guard. This truly makes it easier!

Rated 4 out of 5 by from Good shirt I bought 3 of these shirts and I can say the following: - I typically buy a size large but other reviews suggested these shirts run large so I bought a medium. The medium fits more like an M/L which works for me plus I don’t want a bunch of unnecessary fabric weighing me down. - I like the band of sticky material that keeps the shirt from riding up. Plus the zip feature helps drain the water. The fabric appears to be good quality. - These are a bit pricy (esp converting to CDN) but worth it. I’ve had melanoma twice and can’t afford ( haha) to mess about.

Rated 5 out of 5 by from Awesome Shirt with Great Functionality! I have been using Coolibar shirts and rash guards for over a decade and remain a lifelong wearer. The quarter zip is a nice change as I have always had the pullover. I love the multicolor piping. Better yet is the zippered pockets which are awesome when I am paddle boarding as they work great for a fold-up sun hat and a pair of glasses. Best part is that it provides the awesome sun protection that I have trusted from Coolibar - even after exposing my New England winter skin to the hot Caribbean rays.

Rated 5 out of 5 by from Got great, slimming. Bought this for my husband. Color was very nice and I thought it made him look slimmer. He was thankful he had it as he felt warmer when we went swimming with the stingrays. Product was true to size.

Rated 5 out of 5 by from Best Rash Guard on the Market I own/use a number of Coolibar products and while I pretty much love them all the Zip Rash Guard is my top favorite. Fits great, looks great, feels cool even on hot days, provides the protection I need, and dries quickly. Instead of slathering on layers of SPF on my chest, arms and back every hour or so and then obsessing as to whether I missed a spot, I just put this on and go all day. Runs a bit large in size (I ordered a L where other brands I'm an XL). I prefer the Coolibar guard over my (much tighter) surf rash guards like billabong and O'Neil.

Rated 4 out of 5 by from Great product - very comfortable When are you going to get more of these in stock?? Every time I check back (for several months) it’s only the same one small in white.

Rated 4 out of 5 by from Great Multi Activity Protection While I know the Zip Rash Guard has a focus for activities either pool side or at the beach, it is the kind of shirt I see myself wearing for so much more! Here is the South, we get some days in mid Winter where the temperature climbs into the 60's and the sun is shining. I totally see myself wearing this shirt for a run or light outdoor chores. The rear zipper pocket is perfect for stashing lip balm or your beach house key. The fit is near perfect. At a size Small, the sleeves and chest are spot on with neither being too tight or too loose. The sleeves especially are the perfect length for someone of my height and build. The bottom hem has a silicon gripper to keep it in place. However this is about 2.5 inches longer than I would like - coming all the way over my rear end. My compromise is to fold up the excess. Even with this minor adjustment, the rear pocket is still completely accessible. Overall, I am very excited about this new addition to my sun safe arsenal.
