Fabric Details

Aqua SUNTECT® Classic
This is where it all started! We set out to develop a superior UPF 50+ swim fabric that didn’t feel heavy or rubbery like scuba rash guards. The result is a technically elegant, sun-safe swim fabric that is chlorine and saltwater resistant with a modest 4-way stretch. It’s silky smooth on the inside with a figure-flattering matte surface on the exterior. Customers love our Aqua Classic because it’s lightweight, quick dry and comfortable.

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.

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 Surprisingly Cool! I bought this to wear in south Florida while on vacation since I was recently diagnosed with skin cancer and don't want to do any more damage. I wore it while swimming in the pool and the ocean, as well as while fishing. I love it! I thought I might be hot wearing a jacket in the heat, but I wasn't. After it was wet, it even kept me cooler than without the jacket. As a bonus, it protected my arm from the seaweed that was washing ashore, and I put the shells I collected in the pockets.

Rated 5 out of 5 by from very stylish for office wear or going out It's a slimming color. The zip down front makes it versatile as an open jacket or a fashion top. The front zip pockets and inner drop pokets are very useful for quick errands outside from the office. Space for cell phone, charge card, sunglasses, etc. Thumb holes great to ensure protection from the sun on your hands while driving. The style and colors navy and black are very slimming. I wish the fabric was a little cooler, like the original zip front swim jacket.

Rated 5 out of 5 by from very stylish for work or going out Very flattering jacket. Love the choices of navy, black and olive green. I bought the navy and the black. I would have bought the olive green if it were a little darker olive green. Love the front zip pockets and the inner drop in pockets on each side that are great for my cell phone and sunglasses. Love the zip down front so you can wear it open or zipped up closed. Love the thumb holes to guarantee coverage if your hands while driving. I do wish the fabric was cooler like the original coolibar swim jacket. I received lots of compliments on this jacket at work.

Rated 4 out of 5 by from Becoming shape My first diamond cove jacket in blue print arrived this AM w other purchases. I liked it enough to order another in black size m. The flounce & length work well with Petra pants and leggings. I’m finding m is my Coolibar size except for tees where a S be more body hugging & attractive.Im. 5’5” & prefer 25” length because other tunics are too long.

Rated 5 out of 5 by from You need this rash guard in your life In the last 3 months in prep for summer, I have purchased 8 different long sleeve rash guards trying to find one that not only fits but is flattering to my size 18/42c body. Every single one has gone back. Every single one I ordered went back for the exact same reasons: too tight in the bust, too tight in the hips, too big in the waist and shoulders, sleeves too long and the material too heavy for the beach. While more than I wanted to spend, I figured this was my last shot. So, based on past history with other rash guards, I ordered an XXL, and it was actually too big! I sent it back and got an XL (which is my correct size per coolibar size chart) and to my utter shock and delight, not only does it fit, but is extremely flattering. This rash guard is built for a woman, not a 12 year old boy. The material is absolutely perfect for swimming or boating. Its extremely well made, the zipper goes up and down without a struggle and the fabric is so lightweight it wont weigh me down when wet. Even the side zipper pockets go up and down with ease. I am now a fan for life of these products! Well worth their price. I would love to see this style in short sleeves for really hot days, and in Hawaiian prints! I would buy more!

Rated 5 out of 5 by from Great jacket and so comfortable I wear this everywhere. It is lightweight but comfortable on a windy day. I bought it for the sun factor but wear it everywhere. Need to order another one.

Rated 5 out of 5 by from Excellent Features Lightweight; permanently SPF 50 after washings; complete front closure zipper which makes it much easier to take off when wet; two zippered pockets for hotel key and/or credit card, etc.; wrist "slit" to ensure complete non-slipping coverage. After all my research, this is the very best swim jacket I've found. Coolibar has been highly recommended by my Dermatologist. My only concern is that when ordering as a Canadian customer, it seems extremely difficult/expensive to make a return. Delivery time to Canada was close to 3 weeks.
