The fabric of this swim rash guard feels nearly as soft and silky as fresh, cool water. With a slightly fitted fit, crew neckline, and full-length sleeves with thumbholes, it's an incredibly soft and smart way to enjoy the water and the sun.

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 Beautiful fabric! Thumbs up for sizing down Thanks to the previous reviewer, I took a chance sizing down in this on final sale clearance. I'm small framed and petite in stature but I'm not really skinny: 5'3", 120lb in these Corona times, 34B, 27 or 28 in jeans, S or XS in tops. The XXS fit me like a glove, which is great for not getting saggy or floating up from the body in the water. It's just slightly tight in the armpit area and shoulders, but the fabric is so stretchy and silky, lightweight and cool to the touch, this doesn't bother me at all and is more flattering than a relaxed fit. The neckline is higher and tighter than other crewneck rash guards I've worn (see how model's collarbone is fully covered), but this is a plus for sun protection. The length is perfect, hitting me at low hip when not ruched up. So, if you're on the fence but my size or smaller, I think you'll be happy with this item in XXS if you want a fitted rash guard. What a deal!

Rated 5 out of 5 by from obsessed! This shirt is incredibly lightweight and comfortable and it fits perfectly. I’m usually an XS with Coolibar but sized down to an XXS because I wanted a more snug fit and it’s just right. This pinky purple color is adorable! Love.

Rated 5 out of 5 by from Most Comfortable Top I Own I rep'd this a week ago and have worn it twice. I have to refrain from wearing it more often. It is the most comfortable top I own. The weight of the fabric is just perfect. Substantial enough to make it hang beautifully, keep its shape all day and always have that "fresh out of the laundry" look. But it is also light enough to keep me cool and comfortable in warm- to very-warm weather. I never expect both ends of that spectrum to be satisfied--either it's a nice fabric but is too hot...or nice and cool, but the fabric is skimpy, wrinkly and looks "tired" halfway through the day. And here is a bonus: I got a spot of red raspberry carrying in the groceries the first time I wore it. I was extremely impressed that it washed out with a 2-minute pre-treat and wash. What a bargain, need more colors, please! XL runs true to size.

Rated 5 out of 5 by from Perfect coverage and protection for beach and pool As always, I am delighted with my latest purchase of sun protection clothing from Coolibar. They last, protect and are so nice looking on as well. The patterns give color to the outfit. Extremely pleased. I can now truly enjoy the pool and beach.

Rated 3 out of 5 by from Great shirt and swim shorts Product is comfortable and true to sizing. Very hot with strong sun here, and I was putting on a swimsuit, running shorts and a long sleeve T-shirt. I figured "why'?? so I bought these 2 pieces instead. Easy and comfortable!

Rated 5 out of 5 by from Beautiful pattern in the blue beach palm I loved the light weight soft feeling of the fabric. There was no rubbing under the arms. I received many compliments in water aerobics. One woman thanked me for wearing such happy colors. I bought it with the matching skirt. I will buy the matching bra for a little support.
