Sun Fact

Our work shows that skin cancer risk behaviors, including sunburns, indoor tanning, and lack of protection, peak at age 25. Thus, young adulthood is an important window for skin cancer risk reduction interventions.

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 5 out of 5 by from Long and flattering at same time I just received my long sleeve swim shirt in hot pink and absolutely love it! Long enough to cover black knee length swim shorts to cover butt but beautiful gathering in on the sides to adjust it to length as I desire. I am curious to see how it holds up in water I have no hesitation it will definitely work out in the pool with my kids. I like how it goes up high on the neck since my 4 and 2 year old kids are always pulling at my chest while swimming so no revealing going on there. I ordered XL in shorts and shirt and fits PERFECT. I like that it is not skin tight but still fits with being a bit loser but accentuates my feminine figure with gathering in on sides so my tummy is hidden. Will be careful not to sit in sand at beach to stain the nice pink color of shirt as it covers my butt and if I am not careful that could be an issue. I can always purchase a darker color for sand or other weather. I plan to keep these strictly for pool time at my dad's and when we visit the beach this summer. A bit expensive to wear on a day to day basis being a Mama I would probably ruin it first week of wearing it with my kids always a loving to play outside and get dirty. I keep my kids "pool" bathing suits seperate from play clothes as well just since I also invest in nice sun protection suits for them from Jan and Jul. Anytime I am in a pool or at the beach I am in direct sunlight more than I am on a day to day basis so this outfit is perfect love the catalog that I got for free with it and I will definitely be buying more quality pieces for me in the future.

Rated 4 out of 5 by from Fantastic swim shirt Covers all the right areas, great neck zip for ease of getting on and off and cinches shorter when you want it that way. Only thing missing is thumb holes for better coverage of top of hands….;)

Rated 5 out of 5 by from Nice top offers colorful, lightweight protection This is a pretty top and it fit well. I liked that it can be adjusted to various lengths depending on what bottom is worn. I have some swim leggings, but I don’t have a leggings body, so I appreciated being able to make the top longer with leggings versus shorter for looser swim shorts. I’m curvy with a waist, but my bottom is bigger than my top. I was unsure whether I should size up or down to fit one part not the other. However, the design and cut meant I got a good fit for both bottom and top without having to finesse size choice. I got my usual. A plus: it dries fast.

Rated 5 out of 5 by from I LOVE THIS TOP! I purchased this in Baja Blue Tropical leaves along with the short that match. I bought a size 2x since I normally size up in swimsuits. This is a tiny bit large, but I will keep it as you can adjust the ruching...............Thanks Coolibar for helping all women to become beach beauties at any age !!!

Rated 5 out of 5 by from I LOVE IT!! I love this swim shirt! The length is perfect as it's modest but not old-lady! You can pair this with bikini bottoms, a swim skirt, or swim shorts and it's super cute. Love the print. It almost reads as a neutral, and looks great with solid or striped bottoms in navy or black. The drawstrings on the sides are cute and they're useful for shortening or lengthening the shirt. Very happy with this purchase!
