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 a respected Dermatologist and Mohs Surgeon:

 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.   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 you use a sunscreen that contains the UVA-protecting ingredients of titanium dioxide or zinc oxide.

Perfect cycling baselayer

I have used the cooling sleeves for a while now so I had a good idea what to expect for this top. I know to carry extra water to take full advantage of the cooling properties. I intended to use the top as a cycling base layer on hot days. This worked great for the Belgian Waffle Ride in Utah. Even without pouring water over the top, I could feel the cooling effects throughout the ride. The real advantage was toward the end of the ride which has a tough 3 mile climb and pitches up to 16%. At the end of the day, the hot canyon was 104 F according to my computer. Well, this top worked perfectly I poured my extra water bottle over the baselayer to keep me cool. This allowed me to tackle the climb without stops in the shade. I fared much better than the other riders around me. Overall, I highly recommend the top for any hot events. Just remember to keep an extra bottle of water to maximize the cooling effect. In the future, I hope there's a cycling specific version of this top as a mesh baselayer. I'd be first in line.

Love the colors.

Desoto Apparel has always been my first choice when selecting Triathlon gear. I have been using Desoto clothing for about 25 years. I love the color and the light fabric. As in my other reviews the fabric in breathable and feels sensuous against the skin. I will use this shirt for my next triathlon- whenever everything opens after COVID19.

Great Fabric Good Fit

Just like the title says: the half-zip try top was exactly what I was looking for. I'm glad to support a company that makes clothes right here in the US. Good quality fabric, zipper, and fits me great.

Great Top

Used it in a race shortly after buying and it was awesome! It wasn't even noticeable during the swim which was non wetsuit, also liked the looser fit!
