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.

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.

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 3 out of 5 by from Not as comfortable as previous design I have 3 pairs of swimming shorts and I bought these a few weeks ago before going sailing. These are designed differently and I do not like them. The fabric has pretty much no stretch whatsoever. The cut of the shorts is odd and not comfortable.

Rated 2 out of 5 by from Swim shorts seem different vs. first purchase This was the second pair of these shorts that I purchased so, like before (more than a year ago), I ordered a medium this time. My first black pair still fit (and I weigh the same), but the second navy pair were much too tight and were returned. Perhaps Coolibar has changed manufacturers (or fabric), but these shorts are not the same as those previously purchased.

Rated 5 out of 5 by from Dry time and length I just bought these before my daughter and grandchild came for a visit here in FL. I had weightloss surgery 21 years ago so I have extra upper and lower leg skin at 53 yrs old that I would like to "hide" and these did the trick. I am 5'2 and 140lbs and a small did just fine. They fit snug and dry fast when I dried off with a towel. I love them and plan on ordering more for the summer. Thank you for whoever came up with a great concept!!

Rated 5 out of 5 by from Good Choice I purchased these swim shorts specifically for an upcoming vacation. I am 5 ft. 6 in., 137 lbs. I ordered a size Medium based upon my HIP size, rather than waist size, as I did not want shorts overly large that would "balloon up" when swimming around in the water. My waist size is larger than that indicated in the Coolibar sizing chart, but this is good, as the shorts are nicely snug fitting, so the shorts won't ride down. I am pleased with this purchase.

Rated 5 out of 5 by from So comfortable! I could live in these they are great for just lounging around or doing chores at home or pool. I think I will even use these for exercising! I ordered size small and they fit perfectly. I am 5'4 and weigh 135 pounds I'm a little heavy on the bottom half .

Rated 4 out of 5 by from Comfortable I bought one XL pair and they fit great when dry, but as soon as I got in the pool they felt baggy and bunched up in the crotch. I will order another pair, because I like the quality, but I'm bummed I have to spend more money!

Rated 5 out of 5 by from Good fit, nice material I am always nervous about buying on line. When I recieved the swim shorts I panicked thinking they looked too small. I tried them on and they fit perfectly. I ordered a medium. I love them. I wish I could find just the right top and that's my next quest before our trip to Antiqua. I recommend these shorts.

Rated 5 out of 5 by from Perfect Swim Shorts Ruining a vacation with a sunburn is no fun, and I have the experience so I know what I'm talking about. Purchased two pairs of these before a Hawaiian vacation and they were perfect. Very comfortable and like that the slim fit keeps them from balooning in the water like others I have purchased in the past. They dry in a snap and are so lightweight for packing. I am not slim and they still look good. Am always a bit concerned about looking like an old lady. Paired with a an elbow length rash guard I looked more like I was ready to surf or boogie board even if I was mostly just bobbing in the ocean or lounging around the pool. Very pleased with the fit, performance, and look.

Rated 5 out of 5 by from Fit Just Right These are great, glad I discovered Coolibar. Perfect for anyone but when your legs age and have a little extra cheek fat that you do not want exposed, these are for you. i do a lot of water walking at the pool and they are great, don't hold a lot of water and very flattering.

Rated 5 out of 5 by from Long versatile shorts! This is my second pair! I love the length and fit. It works for swimming, of course, but I also use them for kayaking. Quick drying.

Rated 4 out of 5 by from Fit is Good These are comfortable dry and very true to size bit are not compression style. I wish there was a compression style available so they wouldn't bag when wet.

Rated 5 out of 5 by from Covers a multitude of issues! Recently purchased the shorts after seeing them on someone at the beach. Loved the look and the practical need for me. Wish I could get the bra top and rash guard she had, but you appear to be out of stock.

Rated 5 out of 5 by from Must Have I wore these swimming shorts all week at Lake Powell--swimming, hiking, climbing, scooting, jumping. The fabric is lightweight, but durable. The shorts stay put. The fit is excellent. These are not compression shorts. If you're looking for a tummy tuck, these are not the shorts for you. But if you want a great pair of comfortable swim shorts, get these.

Rated 5 out of 5 by from Great swim shorts I bought my first pair of these and loved them...then bought 2 more. Someone at the pool asked where I got them. They fit and feel so nice and dry quickly. I like the length too!

Rated 4 out of 5 by from Comfortable These are comfortable swim shorts but I wish the material was a bit thicker. They are very clingy when wet.

Rated 1 out of 5 by from Not for me My sister wore her coolibar swim shorts and they looked great so I ordered them. In fact I ended up ordering three pair in different sizes and from coolibar and Amazon in my quest to find a pair that worked. I really wanted these. Didn't like the material of the current shorts. It rides up when you walk. And the sizing was strange on all of them. The waist was really tight. Tried 3 sizes. All too tight. Returning them all.

Rated 5 out of 5 by from These are amazing I love wearing these swin shorts...they stay in place and are so comfy. Love the length as well, so very hard to find shorts that fit the thicker person that look decent and go close to the knee area. Well worth the price and I would for sure order them again.

Rated 5 out of 5 by from Great shorts Fit great and have good support. I usually wear petite 10 and the medium fit perfectly, covering legs to just above knees.

Rated 5 out of 5 by from Perfect diving short These swim shorts were purchased to be worn under a lycra skin for scuba diving in the Caribbean. As a woman in my 50s, these swim shorts provided the coverage I desired and were perfect under my lycra skin. I also purchased a swim bra to go under a sleeveless swim shirt I was given as a gift. This threesome was an absolutely perfect combo for diving. I only wish I'd purchased a second threesome so that I didn't have to worry about getting them dry before the next day's dives! But, not to worry, they dried quickly and became my daily dive outfit! Perfect combo, Coolibar!!

Rated 5 out of 5 by from Great water shorts I used these shorts on a seven-day kayak trip down the river. They are very comfortable and dry almost as soon as they get wet. I have large hips, but I still have an hour-glass figure, so the small piece of elastic in the waist made these shorts quite functional for me. They are a little expensive to "play in the river", but, I will definitely get another pair. I guess you get what you pay for.

Rated 5 out of 5 by from Better design! Much better since they changed the tight elastic waistband. The smooth band is great!
