Features & Benefits: 

  • Made of Polartec® Power Stretch® fabric is highly breathable and doesn’t restrict movement of moisture vapor. “Touch Points” on the fabric inner surface work to wick sweat off the skin to the outside of the fabric, where it rapidly evaporates. Body-hugging, 4-way stretch allows unrestricted movement. The tight knit makes this fabric wind resistant, and provides warmth without the weight of traditional insulating fabrics.
  • Long length sleeves with thumb holes for added warmth to the hands.
  • YKK full front zipper for durability as well as easy in donning and removing.
  • Relaxed neck design eliminates zipper rubbing when zipped up. 
  • Neck collar is lined with MicroSurf™ Stretch for added wind resistance and a smooth neck surface.
  • Left chest pocket made of MicroSurf ™ Stretch, with 7" YKK zipper large enough to hold sunglasses and large-sized smartphones.
  • Made in the USA

Second One

I love this jacket, it is my second one and I use it all winter long. The jacket fits and feels amazing and keeps my body temperature even. Perfect for the cold winters we have here in the North.

Definitely Get One

Another great Desoto product. Fits great. Very warm on the bike with temperatures in the 20’s. You don’t feel the wind either. Love it. Thanks

Garment choices

Garment choices are key when it comes to wanting comfort and performance. The El Capitan Trail had everything. Morning temperatures at 24 degrees, in the first 3 miles I was drenched in sweat climbing 3,000 vertical feet straight up, I then hit 5 miles of snow and temperatures back in the 20’s to greet beautiful sunshine at the summit. Emilio De Soto’s De Soto Sport & Mask Company’s CHAMONIX FLEECE JACKET & POLYPRO THERMAL TOP was absolutely the right call. Never cold, wet (from sweat) and they are extremely light and allowed me to move quickly, not feeling like I was bogged down. Thank you for helping me accomplish one of my better days I can remember!!

Out of the blue the other day my husband said, "that jacket is a great jacket". After determining he was speaking of the DeSoto fleece jacket I recently purchased for him. I queried him as to why he made that statement and he said the fabric is so soft and the fit is perfect. He is 6'1" and weighs 195. We bought the large. He has not had the opportunity to use it on the mountain bike trails yet as he is recovering from knee surgery. I am such a DeSoto advocate and was happy I could get this jacket for him. I love my fleece pants and wear them constantly for my winter runs. Thank you.

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.
