Keep yourself cool and protect yourself from the sun with this De Soto Innovation - A cyclist’s Bolero style top.

Sizing: Please refer to the size chart button above, for guidance on how to achieve the right fit. Sizing is based on "wingspan" measured across your back, standing up, from wrist bone to wrist bone.  If your measurement is a little over those shown, don't worry,  this fabric stretches a lot and you want the Coolwings to be SNUG against your skin.

Fit Type: Form fitting.
Fit Note:
 Please do not assume your size, please use our size chart. If in doubt, email questions to Triathlon apparel is meant to fit next-to-skin. This is to eliminate potential chafing, and unnecessary drag during the swim, bike and run. If you’re not comfortable with this type of fit and or are between sizes, we recommend sizing up. Garment will fit the most snug the first time you put it on, it will relax slightly once wet.

Features and Benefits:

  • Skin Cooler 90™  fabric stretches with you, is soft next-to-skin and breathable
  • Fabric blocks 90% UVB rays and provides a cooling sensation when wet
  • Reflective logos for increased low-light visibility
  • Covers the shoulders, upper back, and arms
  • Wear it over or under any top.
  • We are often imitated.  Remember just because it is white, it does not mean the fabric will cool you.  READ ON!

What makes ours different?  Our Skin Cooler fiber is designed to feel and perform like silk (from a silkworm).  Through Biomimicry, we took the virtues of this natural fiber and created a synthetic silk.  It will keep you cool in hot weather and cooler when it is wet.  Put it on and you will instantly feel the cool sensation.  Wet it and you will notice a drop in the surface temperature of the skin between 7 and 10 degrees.

A MEDICAL TESTIM0NIAL:  We received this letter from Dermatologist and Mohs Surgeon Dr. Michael Bax.* 

 I am an avid runner and triathlete and I recently discovered your Skin Cooler products, of which I'm a huge fan.  I have been wearing them for a few months now and couldn't be happier.  I am a dermatologist and Mohs surgeon at Roswell Park Cancer Institute in Buffalo, NY.  Every patient I see is plagued by basal cell carcinoma, squamous cell carcinoma, or melanoma.  I recommend your products to my active patients on a daily basis.  It allows them to continue their active lifestyle while protecting themselves from the sun. I find your product to be far superior to all other cooling and sun protective lines.  I truly appreciate your efforts and innovations.

Note: No garment should ever be a substitute so we always recommend you wear sunscreen underneath these, and all, products. It is crucial to keep in mind that a sunscreen's (whichever brand you may choose) SPF/UPF rating refers only to its ability to protect skin from UVB radiation. Because we know that UVA damage can be just as insidious, it is essential for the health of your skin that contains the UVA-protecting ingredients of titanium dioxide or zinc oxide.

The best sun sleeves!

These are the only sun sleeves that actually make you feel cooler when you sweat!

Cooler than bare arms

These are easy to put on and have kept me cool biking and running in hot humid weather. I liked my arm sleeves, but these are easier to put on and I don't have to worry about them falling down! Love them!

These are the best

I have an old mesh set of these and the new ones are higher spf and smooth fabric. Much better than arm coolers as they do not fall down. Very cooling when wet. I am 5’3 115 lbs and a medium fits well, perhaps a small would have worked

Love my coolwings

I’ve had a different brand, but sold them after trying coolwings. There is no binding feeling around the shoulders or under your arm—and they actually do feel cooler the second you put them on. The spf factor is a big seller for me, too!

Functional and Nice looking

The Coolwings "cooler" bolero worked great in a recent race. I like to keep my arms covered from the sun and also because I am sometimes a bit chilled at the beginning of the run. Arm sleeves alone don't cover your shoulders and I tend to have trouble keeping them up (skinny arms). I honestly wasn't aware of having the cooler on and when I started sweating, they did cool me. I would highly recommend this product. Also, the Site had an issue with delivering the item when promised but they were very good about touching base with me and letting me know and giving me an option to cancel the purchase if I wanted to. The delay was only a few days.
