We created this limited edition shirt to commemorate our 30th year in Kailua-Kona, Hawaii for the Ironman Triathlon World Championship.  Being a San Diego, California company so heavily influenced by a sport which is so deeply rooted in a healthy lifestyle, endurance, fitness, and our mother ocean, we wanted to create something special, and technical, for you.  Wear it to dinner, to yoga, or on a 20-mile run.  

Skin Cooler™ Silk is a knit fabric with small pin-holes on the outer surface, and a smooth silky inner surface.  So light and cool you need to try it!

Be cool, be comfortable, be is too short to wear crummy workout apparel. There are good tech-t's and there are bad tech-t's. The ones you get for cheap are bad, and the ones you get for free are cheap.  If you are looking for a technical t-shirt that really works here is our second version containing the Skin Cooler™ fiber.  

Sizing: Please refer to the size chart button above for sizing guidance. 

Fit Type: Relaxed Fit - not baggy and loose, but not skin tight.  If you own any other De Soto Top and you are happy with the fit, we highly recommend you go with the same size. 
Fit Note:
 This is a knit fabric so it does have stretch around the torso (horizontal stretch), but there is no elastane in it so there is almost no stretch up and down (similar to a woven dress shirt).  If you own any of our other Skin Cooler tops, you will wear the same size, yet it will rest more loosely.

Please do not assume your size, please use our size chart. If in doubt, email questions to 

Features and Benefits: 

  • Skin Cooler™ Silk is a knit fabric with small pin-holes on the outer surface, and a smooth silky inner surface. You get a light weight t-shirt with a slight stretch round the body. 
  • Skin Cooler™ Silk fabric blocks 90% UVB rays while remaining breathable and cool due to the smooth finish combined with .  
  • Cooling is caused by the pin-holes combined created by the knit in the fabric.
  • This shirt will not shrink, but may fade over time.
  • Offset seams eliminate the potential to chafe.
    • This is not a compression garment, and is designed from both training and for workouts where aerodynamics are not as important.
    • This garment is one product which comprises the less than 2% of our total products which are not made in the USA.

    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.

    The size chart above should serve as a general guide. If you would like assistance in determining the proper size, please send the following information to

    WEIGHT - Accuracy helps us provide a more accurate size for you.
    CHEST - Fullest part of breast, measured as the largest part of circumference right over the pectoral muscle.
    WAIST -  Circumference measured at the belly-button line - this is NOT the same as your pants waist size.
    HIPS - Circumference measured at the widest point, NOT at your hips where your belt may go. Typically this will measure just a few inches below your hip bones and around the largest part of the glutes.

    If you do not have a tape measure and you need something to measure with, use a belt, or smart phone power cord, and a ruler.
