Men's Skin Cooler Full Zip Top - Laser

LASER stands for Light Amplification by Stimulated Emission of Radiation, but most people simply know it as a beam of parallel light. Inspired by this concept, we designed our SkinCooler Silk Tech Tees, which became so successful that we named the entire collection LASER.

The LASER collection represents more than just innovative garments—it embodies the idea of staying sharply focused on your goals. Just like a laser beam, it encourages you to maintain a clear, unwavering path toward success, cutting through distractions with precision and intensity.

We hope this collection inspires you to remain "LASER-focused" on your ambitions, staying cool under pressure and directed toward achievement.

This is our most technologically advanced top and the best money can buy. It has a blend of two very light fabrics with the entire back and sleeves made of our Skin Cooler 90.

Fit Type: Form fitting 
Fit Note: Please do not assume your size, please use our size chart. If in doubt, email questions to contact@desotosport.com. 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.

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.
