Fabric Details
Aqua Helios™ FabricAqua Helios™ Fabric
Our Aqua Helios fabric provides medium compression for added support and shape retention. With a slick handfeel, chlorine and saltwater resistance and 4-way stretch, this breathable, quick-dry UPF 50+ fabric is designed for active water wear. We developed it as a sustainable fabric made with a recycled fiber blend and Lycra® Xtra Life™ to resist perspiration and wear from chlorinated water up to 10 times longer than most spandex.

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 5 out of 5 by from Built in cups! What I love best about the Escalante rash guards (I have three now!) is the built-in cups that allow it to be full-function swimwear without the addition of a second bikini or tankini top for those of us who are larger busted. Great materials, but I'd like to see more coordination with the swim tights, please!

Rated 5 out of 5 by from Fit The inside bra part is really really loose, but the outside is very comfortable. The shirt is very pretty and I like it very much.

Rated 5 out of 5 by from LOVE This so much - perfect fit and weight I love this Rashguard. I wear a size 12 and I purchased a Medium in this top. I have larger breasts that are not as shapely prior to kids and this too held them in place almost like a sports bra. It has built in padding which normally I always pull out but it was the perfect amount and didn’t define a breast region - it just gave me extra coverage which I loved and could not even tell the pads were there. I received a lot of compliments - it’s very slimming with the design of stripes coupled with the solid black color.

Rated 3 out of 5 by from Runs small LOVE the print and longer zipper, but definitely runs on the small side. Please bring this back in this print!

Rated 5 out of 5 by from Big sun for a big gal I'm a bigger gal (275lbs/5'4") and usually "active wear" doesn't fit me. But the 3X of this did, comfortably (if sleekly) and it totally rocked. I spent several days in it, out in the sun and with lots of time in the water, and had no sun troubles (and it dried nicely fast!) Looks great with the matching teal leggings. Can't wait to wear it stand-up paddle-boarding!

Rated 2 out of 5 by from Beware of sizing & cut! This garment is cut for a slim woman with long lean arms and long torso. It is very claustrophobic to put on and remove. I am willing to try a larger size but am disappointed. The matching bra top was the same problem and unfortunately I kept it but feel little joy in wearing it. On the whole, Coolibar sizing tends to run large especially with rashguards but I have noticed their sizing isn't as consistent as it once was although the overall quality of the clothing continues to be high.

Rated 5 out of 5 by from Fit and good quality product Fits very well! Bought the XL for I am 6 feet and 195 pounds... While swiming it keeps its form and after, it dried quickly.... I recommended this garment to family.

Rated 5 out of 5 by from Stylish Rash Guard I love this stylish rash guard. I am actually wearing it now! It looks/fits just as pictured in the catalog. It's very comfortable and I feel super-confident that I am protecting my skin without greasy sunblock lotions. Thank you, Coolibar!!
