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 Light comfortable fabric that wears well I found these on sale, and decided to try them out. I light how light and airy they are, and not too cool for California winters - it's been in the 50's. The side slits are a bit longer than I realized, and the 3x is pretty large - the elastic band hangs on me and is not adjustible with the tie string. Wish I would have purchased the 2x instead.

Rated 1 out of 5 by from Damaged Arrived with a large pull on the back of the leg. Bought on sale but still don't feel they should send damaged goods. These are super delicate apparently. Caution.

Rated 4 out of 5 by from Light weight sun protection Size extra small, black & white for sun protection cruising on sailboat, hiking or walking. I am 5’2”, 107 lbs. Had taken in a lot from pockets down sides with 2” slit at bottom. No heming needed for full length on me. Work well in hot dry weather (Montana), haven’t tried sailing in humid conditions on Chesapeake Bay.

Rated 4 out of 5 by from Cool, comfy, funky but inconsistent sizing I have these in the taupe print and in black and they fit great. Love them. So light and airy. Dressy yet can be worn with a swimsuit. I bought another pair in the black/white geo print in the same size. Unfortunately these are too short in the crotch and I will need to return them. Very disappointing to have to pay for return shipping on something you would expect to fit the same.

Rated 5 out of 5 by from Fun, sassy These pants are delightful and fun. Fit runs true to size, easy to care for, and looks great for casual and dress up. Great for travel as you can use them for many events. I can't say enough fun things about these pants!! Get a pair and discover the sassy feeling on your own!

Rated 5 out of 5 by from So comfy and stylish! I love these pants. They are incredibly lightweight. The ability to tie them makes them just a little funky, and they're easy to dress up or down. One caution is that they run pretty large. I had to go one size down and maybe should have gone two sizes down from my usual Coolibar sizing. Still, I love them!

Rated 2 out of 5 by from See through pockets! I bought these back in February. They made my legs look huge and the see through pockets, well, that just didn't help. Sorry, not for me!

Rated 4 out of 5 by from So light and airy This fit perfectly and looks casually elegant. I had to hem mine because I'm short, but that was simple. The biggest issue I have with them, though, is that they are pretty see-through. You can see your underwear through them quite easily. I bought them to wear over a swimsuit on the beach, so I don't mind that, but be warned. I have never had a lighter and more flowy pair of pants, though. You will stay cool in them!

Rated 3 out of 5 by from Love the fabric but cut doesn’t work for me I really wanted to love these pants, but I seem to have the same problem with all Coolibar pants: the waistband feels cheap and stringy, and there is no shape or styling so the fabric bunches out and ruins the line of my top. This particular pair was just too short in the crotch too, so it didn’t sit nicely on my waistline. I am 5’8 and 150lb and the Medium was the one I tried. It’s such a pity, as the fabric is fabulous and the lower leg styling is gorgeous. Coolibar, please invest in some better styling and fit for the waist sections of your pants!

Rated 5 out of 5 by from Great Fabric! I loved these pants so much that I ordered another color. The fabric is light as air and extremely comfortable, moves nicely.

Rated 4 out of 5 by from white is see-through These are supremely comfortable but the white is totally see-through (you can see cellulite) so I am going to exchange for a different color.

Rated 5 out of 5 by from Unique and comfortable Bought these pants for our trip to Amelia Island; they can be casual or dressed up. Perfect for the summer. The material is maybe like parachute material; makes them thinner/ cooler but I wear tops to cover my bum so not a problem for me. They are unique to any other white pants I have or see out there, tied up or open leg, easy to wash and dry means less to pack.

Rated 3 out of 5 by from Great summer fabric but not for short people I loved the light fabric; should be great for summer. However the fit was just not flattering to my 5’4” frame. I think it would have looked better if a petite size was available, as the design is cute and comfortable. Should look fine on a tall person.

Rated 5 out of 5 by from Great pants! Great pants! Bought these for A trip to the Caribbean. These are the best pants ever. Provide excellent coverage and are super fast drying. They are a great addition to any hot weather trip wardrobe.

Rated 5 out of 5 by from love the fabric! I love these pants with three knots tied... so cute. the fabric is so light and cool it's amazing.

Rated 5 out of 5 by from Perfect for warmer temps! I love the fabric as they will be perfect for warmer temperatures. The fit was perfect--I am a pear shape with 28" waist and 39" hips and the small fit very well. I love them tied and will probably wear this way with a flat or wedge sandal.

Rated 5 out of 5 by from Perfect sun protection pant for hot weather Thin material is thin, soft and comfortable, but not see through or figure hugging. Would pack easily and compactly. Have not worn in hot weather yet, but looks like it would be cool and airy, the purpose I bought them for. The color tan is true to the picture. A little long on my 5'2" frame to wear with flats, but would be perfect with a small heel or tied up. True to size, maybe even a little roomy. My hips are 38" waist 28" and I bought a small.

Rated 5 out of 5 by from Light as air! I will likely end up buying everything Coolibar makes with this fabric, it is a dream! I live in a sub tropical climate so the prospect of wearing clothing for sun protection was not appealing but these pants are a treat. Thank you! I wear size 12 and bought these in Large, perfect fit.

Rated 5 out of 5 by from Beach pants I love the fit , comfy and cool. They are going to be perfect for the beach or pool side.

Rated 5 out of 5 by from Perfect travel pants! I bought these pants to take on vacation to the beach where I spend a lot of time biking. I loved that I could tie the ankles so that the fabric would not get stuck in the bike chain. They look cute tied or loose. The fabric is amazing. It is cool, comfortable and dries quickly. It was so hot that I actually sprayed myself with a hose before I walked from the pool to the beach. I was cooled as the breeze hit these pants!! I am 5'9" and 150 lbs, athletic build and size Small was the perfect length and fit.

Rated 5 out of 5 by from Oh so nice! Really like these. I bought 3 but had to return for a smaller size. Reordered and received them promptly. Lots of fabric but they do run large. So comfortable...I've been wearing them all the time.

Rated 5 out of 5 by from Perfect Fit Normally I have issues with pants fitting me but these fit my body perfectly and are incredibly comfortable. They even look cute without being tied up!
Date published: 2017-06-15
Rated 5 out of 5 by from Great style and fit I ordered the Aztec geo print and have no doubt that I will wear them often. They are very light and comfortable and look beautiful tied or open legged. The fabric is classy and feels great to the skin. The waist can be worn below the navel or higher depending on preference and is very comfortable. I just may need another pair!
