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.


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 4 out of 5 by from Love the fit. My new blue swim shirt is pretty and I like that it has a flattering fit. Hoping it holds up better than the last Coolibar Diamond Cove swim jacket I bought 4- 5 months ago; its Seams had been unraveling & disintegrating and it's falling apart. The fabric is strong, color on that one is good so SPF factor probably is ok. It's mainly poor workmanship; it should last longer than that for the price. I like the look I'll try again and hope the new blue one lasts longer.

Rated 2 out of 5 by from Diappointing! This is the second top that I have in this style....I ordered the same size as the first...a medium....but the top I received is not the same fit....in fact I probably need a large...the fabric is different...that is fine as I really like it...but I am terribly disappointed in the fact that there is no consistency between the two sizes.... I am now at the point of not clearly understanding my size.....even with an identical style. Not good!

Rated 4 out of 5 by from great travel jacket and over pilates tees This olive jacket is the second Diamond cove . I bought a L this time to wear over a tee . I've reviewed the previous black M and prefer it for wear with tights. I wish this came in red or burgundy.

Rated 4 out of 5 by from So cute I ended up returning this water jacket because it didn't fit my pear shaped body well. My shoulders are narrow & my rear end is (too wide) and I just didn't think it was flattering. I'm a size 12 top/ 14 bottom, 36DD chest - ordered a size L & it fit as expected, slightly large at the shoulders/ top. I think if I got this in a size M (to fit my small shoulders better) in black - it would have been perfect, although too short... The olive color looked strange to me, & I generally like that color. The issues I had with this are mine - not the jacket's fault. Coolibar, please make more cute/ feminine jackets like this - a few inches longer and in the ZNO fabric & I would buy them all!
