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 Love This is a wonderfully designed and high performance jacket for hiking and being outdoors to exercise. I wear a Coolibar sport hat under the hood for shade over my face and it keeps the hood from coming into contact with my sunscreen. I absolutely love this jacket. It is flattering and very comfortable too.

Rated 5 out of 5 by from Perfect Protection I am really enjoying this jacket. I will be taking it on a trip to the Southwest soon. I still like to wear my Coolibar baseball-style hat under the hood and my pony tail goes through the back of my hat and the hood easily. I like how the two work together so I still have shade over my face and so my sunscreen doesn't come into contact with the hood. The fabric is light, but has a forgiving stretch and the coverage is excellent all the way to the fingers. I am a stage III melanoma survivor and appreciate being able to have confidence to have outside experiences walking and hiking.

Rated 5 out of 5 by from Amazing product It’s an amazing product. I love it! It’s comfortable. I will buy the black one too. I even used it like a bathing suit cover. I’m 5’2

Rated 4 out of 5 by from Nice but could be a better fit Cut of this product, if you have curves, means you have to go up a size.

Rated 5 out of 5 by from Awesome coverage! I just got this jacket and am so excited to finally have a lightweight fitness jacket to wear over my tank tops. I love the length of this jacket- it has just the right amount of rear coverage. I was surprised that this style ran a full size larger than my other fitness pieces from Coolibar. I consistently wear a Large in the fitness collection but needed this style in a Medium. It will be getting a lot of use this summer!

Rated 4 out of 5 by from Nice Jacket I ordered (Medium) a size larger than my usual size because it makes clothing look better with leggings. I usually am a size 6 or a small in tops or dresses. Knowing what to expect really helps when ordering so I'll share my experience. It feels small at the shoulders, small at the bust but not as much, relaxed fit at the waist, and wide at the hips. The hand coverage is more than many items offer as it stays over the hand even when you move and the hood shields the face from the sun better than most. The hood will cup at your forehead and touch your sunscreen so you'll want to avoid chemical sunscreens cause it will turn it orange (most know this.) The arms could stand to be a little longer so they can drape easily w/no pull lines when the arms are straight. This jacket will have to be retired a little early cause of all the sticker type logos that will be coming off before too long. The fabric is wonderful as as expected for an athletic fabric. It is thin so it won't be too hot to use all summer when we have triple digits for months in a row. I have long hair so I greatly appreciate the hair hole in the hood. The sitewide sale right after I ordered and before it arrived was not so fun though and prob won't increase the times I place an order in the future. Overall, I will be making good use of this item this spring, summer, and fall.
