Fabric Details
Aqua SUNTECT® Classic
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.

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 4 out of 5 by from Great I've been testing many swim tops, and these two shirts work quite well. They are light weight and stay put in the water. And I love the patterns. With the addition of a thumbhole I would have given 5 stars!

Rated 5 out of 5 by from Terrific shirt My sister had one of these shirts on when we went on vacation last year. Of course, I asked her why she was wearing a long-sleeved shirt at the beach. After she explained, I thought it was a great idea so I ordered one. The shirt is comfortable and feels light. I can’t wait to wear it this summer. And, of course, it protects you from the sun no matter where you are. At the beach, the swimming pool, working in the garden, or just outside playing with your dog! I am very happy and satisfied with my Coolibar purchase.

Rated 5 out of 5 by from works so well as a "sunscreen" I am 5' 3.5" tall and weigh 123 lbs--34-28-38 (pear) and the size XS fits perfectly. I wear these for walking because these shirts work so much better than sunscreen. The only con is they are a little long and I may hem it.

Rated 4 out of 5 by from SO CLOSE, so sad I'm 5' 3.5", pear-shaped, and about 45 pounds overweight. My measurements are my measurements are 38C-38-47, which places me between Coolibar’s XL and XXL sizes. I bought this item in size L because I wanted it to fit snugly for lap swimming. The shirt is perfect in every way, except it's still too big - like, shockingly big! I have to pull it down when I take a break & just stand in the water, as it rides up a bit while I'm swimming & the hem just starts to float upwards when I'm standing. Everything else about this shirt is wonderful, though, and I wore this as a regular top to work one day and everyone thought it was just a long-sleeved tee. I came back to order a size Medium but they're out of the black & white stripes, which is why I'm so sad. But because I love it so, I'm going to keep swimming in the one I have for the rest of this year & just hope that they re-stock it next year so that I can get one that will stay down.

Rated 5 out of 5 by from Amazing, comfortable swimwear My mother bought me this swim shirt in preparation for a trip to Florida. As someone who is young, fair, and (I like to think) stylish, I didn't want something that would cramp my style while I remained sun-safe. She gifted me the shirt size S (I'm 5'5" and 135lbs, generally wear size small) in white and it's perfect! I spent the whole week wearing it on the beach - comfortable and breathable. It does fit a little tighter in the arms and looser in the stomach area, but I think this is intentional because you don't want the shirt shifting around too much while you swim. Love this shirt!

Rated 4 out of 5 by from Fits well The fit on this is nice. Not suction cup tight, a little loose, but not baggy by any means. Length is nice too. Haven't tried it in the water yet- if that goes well and the color holds up, it'll be a 5!

Rated 5 out of 5 by from Happy and Protected So nice to swim in this shirt without fear of burning. I ordered the size that would fit me snugly but it's still very comfortable in the water. It's a sporty cut so I like the way it looks out of the water, too.

Being of Welsh background with Freckles and barely tanning skin, growing up in Calif........this all added up to A better than average chance of skin damage. I love this shirt! Have two....need more. My only advice.....buy!

Rated 5 out of 5 by from Great shirt: comfortable sleeves and no zippers. I have a several swim shirts and noticed the sleeves are too tight. Finally, I bought this shirt which no zippers and no tight sleeves. I love it. I wear it when I'm not in mood of swimming for a long day. If you don't like zipper around your neck nor tight sleeves, I would recommend this shirt.

Rated 5 out of 5 by from As always, another great product from Coolbar! This is my 6th top from Coolbar. I love their products. A bit pricey but well worth it. Nice fitted shirt. I especially like the high neckline as I have a scar I need to keep out of the sun for a year.

Rated 5 out of 5 by from Love this shirt! I bought this shirt to wear in the ocean and fresh water during the height of summer. It is fabulous! It did not ride up, gave me excellent sun protection, and allowed me to swim in the middle of the day without worry. It restored my ability to do something I love and it looks nice, to boot.

Rated 5 out of 5 by from Perfect! I purchased this shirt because I needed extra sun protection when we go kayaking, sailing and other outdoor activities. It is a very comfortable fit and lightweight to wear even in the summer heat. Also dries quick after getting wet.

Rated 4 out of 5 by from Worth the Money! I love this shirt - not as tight as a rash guard but fitted. I chose the light blue color which is about the same color as pool water. This required me to purchase a nude colored padded bra to wear underneath (unless you don't mind colors/patterns showing through). I only wish it had thumb holes! I had an unfortunate mud incident with this shirt. I chose to hand wash and then wash in the washing machine and it did not stain. Yea! Overall, great shirt and a wonderful purchase.

Rated 5 out of 5 by from Very comfortable I have melanoma and the thought of putting on suntan lotion all over my entire body, every time I walk outside, is tiresome but a most. With these shirts, I need not apply all over. I ordered the sports swim bra to wear underneath and it is very comfortable. It cannot be warn w/o something underneath. I have SPF 50 protection with a shirt. Wonderful!!

Rated 5 out of 5 by from Good fit and comfort I used it while on paddle board. Although I have not gotten in (totally cold mountain lake) to get wet, I think it will be great in the water as well.

Rated 5 out of 5 by from Complete Exilleration I purchased this coolibar shirt to wear as a swimsuit top. My intention was to provide complete coverage for myself, and to allow for a more supportive foundation (bra) underneath. This shirt offers so much more. It is beautiful, extremely flattering, and of superior quality. The shirt dries quickly and holds its shape. Best of all, sunburn is a thing of the past.

Rated 5 out of 5 by from Exactly what I needed! I have two of these; I bought them for a trip to Puerto Rico next month. I wanted to try them out in the water and out and about to be sure they would work for my trip. They fit to size, are very cool and breathable, and protect me from getting sunburned! In the pool, they do not ride up or feel heavy. This is a perfect top to wear on land or in the water, and I plan to do both on my trip! Thanks Coolibar!
