This new Skin Cooler™ Silk fabric is knitted into small square tiles that provide more breathability between the squares and cooling within the squares. This shirt has the same cut and fit as the original Skin Cooler Silk and Skin Cooler Honeycomb Tech Tees. The result is loose-fitting cool comfort at a very affordable price.

GLACIER (Recycled Fiber) This particular color is made with a mill-certified recycled fiber. The Glacier color is the fiber in its raw state, so it has no dye.  While we have been using recycled fibers for over 25 years in our fleece fabrics, this is our first attempt in Skin Cooler. The sales of this product is a test to gauge your interest in a more environmental approach. It is a more complex and costly process. This is why it is more expensive than the Tahoe Blue.


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 you can stop looking.  

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

    • This is not a compression garment, and is designed from both training and for workouts where aerodynamics are not as important.

    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.

    My Favorite Running Shirt

    These shirts are so awesome I bought a few! I have been running for decades and have worn running shirts made from a variety of materials, from cotton to tech fabrics. They all had their strengths and weaknesses, but these shirts are basically perfect. They are light, breathable, comfortable, and not too baggy or too tight. The other thing I love about these shirts is that I don’t need to apply Body Glide to my lats, inner bicep area, or nipples. In other words, I have never experienced chafing with these shirts no matter the distance I have run. I should also mention that the sizing advice in the description is spot-on. I wear an XL in the Skin Cooler full-zip top and the XL in this shirt fits me perfectly. I highly recommend this shirt. You will not be disappointed!

    Super comfortable shirt

    My De Soto Skin Cooler Silk Tee is great. It is very light and super comfortable. The fit is relaxed and the size L fits me very well at 5’11” and 205 lbs.

    Love skin cooler

    Fits very well and it’s great for the heat but also as a comfortable under layer in cold weather.

    Love this shirt

    My new go-to tee shirt at the track or during strength training. Super soft and lightweight. Really appreciate the recycled fabric and all the companies that are moving toward recycled textiles. Fit is loose compared to the stretch fabrics, but still form fitting and not baggy.

    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.
