Sun Fact

Over time, the sun's rays can seriously damage the eyes and surrounding skin, sometimes leading to vision loss and conditions from cataracts and macular degeneration to eye and eyelid cancers. The best defense is sunglasses with high quality lenses that absorb or block 99-100% of UVA/UVB light.
- Skin Cancer Foundation


Aqua Classic™ Fabric

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.

100% Polyester

Rated 1 out of 5 by from Caution - this is a short shirt! This shirt is very short. No long version is available, so that is very unfortunate. It appears to be shorter than a standard length shirt. It’s too bad that they choose to skimp like this.

Rated 4 out of 5 by from Great product, horrible service My husband is 6’8” and the arm length was great. We wish it was a few inches longer in the torso, but overall love the shirt. Coolibars customer service representative was horrible. She was rude and short with me on the phone. When I inquired why I hadn’t received an email about the product being mailed, she obviously lied and said they were soooo backed up. Then all of the sudden, we get an email that afternoon that it had been shipped. Everything about the experience was fine except for the woman I spoke with on the phone. Completely rude!

Rated 5 out of 5 by from Great walking shirt. Great fit, and texture. I have had 3 skin cancers cut off before age 60. I feel it’s important to protect my skin when out walking for prolonged workouts. This shirt, which goes up on my neck, is just the ticket.

Rated 5 out of 5 by from Really nice rushguard! Great quality item! Fabric, fit and style - all is great. Beautiful red color. Fit is true to size. My husband is between sizes L and XL in shirts. We ordered initially XL, then returned it and reordered L, which was perfect. Don’t size up!

Rated 4 out of 5 by from No rubber The one order last year had rubber, not this one. Wish it did. The rubber keeps it from floating up in water.

Rated 5 out of 5 by from Nice shirt but bad delivery My husband loved the shirt, but it took over 3 weeks to get here! Covid was the excuse, but other things I order online weren't delayed. I would not order again from this company because of it

Rated 4 out of 5 by from Met expectations I was looking for a carbon copy of the same Rash Guard Black Solid that I had purchased a couple of years ago. The quality & fabric of my recent purchase matches that of my prior purchase- but it is NOT Black Solid. It has a gray stripe/pipping around the neck & sleeves that really detracts from what would otherwise be the classic solid black look I was after . I hope that in the near future you will be offering your Rash Guard line with an options in all colors that are truly SOLID & without any contrasting stripes/pipping.

Rated 5 out of 5 by from Rash Guard I bought this rash guard for my husband and he absolutely loves it. This garment is high quality, very durable, and washes well. I recommend it to anyone who is looking for good coverage from the sun.

Rated 5 out of 5 by from Perfect protection I bought 2 swim shirts for my husband to wear under his softball uniform and any other time he's in the sun. (Coolibar had been recommended by his dermatologist.) He loved how cool he is despite the long sleeves and how soft the material stays. I like how easy it is to launder. I have now purchased this shirt, and similar, for our adult children and for the grandchildren. Truly a gift of love.

Rated 5 out of 5 by from Perfect for snorkeling Purchased this swim jacket for our week long snorkeling trip around the USVI and the BVI's and it was awesome! Easy to take off after a snorkel to hang out and dry between boating to the next island. I washed it in the tub between days, to avoid ocean smells, and the color is still vibrant and like new. I'm 5'5" and 124# and the size small fit perfect.

Rated 5 out of 5 by from Use them for snorkeling / mountain bike riding This is a great product! Light weight , keeps you cool and the protective collar helps from getting sunburned on my neck. Bought some several years ago and returned to purchase more but not as many colors offered like before. I hope Coolibar will not discontinue this product.

Rated 5 out of 5 by from Saved My Skin in Cancun This long sleeved swim shirt was a life saver on the beach in Mexico. Sunscreen can only do so much, but this great shirt made it possible for me to play on the beach with my grandchildren for hours. I think I need another one.

Rated 4 out of 5 by from great idea I battle precancerous spots and this really helps. I don't like things too tight, but in retrospect I wish I had bought the medium. the sizes are true. it does dry wq1uickly
Date published: 2016-04-05
Rated 5 out of 5 by from Great features Long enough sleeves for my tall husband. Long enough in torso and enough fabric so that it drapes instead of stretches around the wide parts. The blue grey is a great muted color that will blend with whatever trunks he wears. He hasn't used it on the beach yet, but is expecting a good experience.
