Perfect fit, perfect material

Very warm, still breathable and great for 6 months out of the year. Even better for the other 6!

Another awesome product!

Canadian here who does a lot of Nordic skiing, alpine skiing, snowshoeing and winter running. I needed something warm but not too warm when doing higher intensity workouts. This thermal top is fantastic for all of these sports. For Nordic skiing and running, it’s perfect on its own and plenty warm. For alpine skiing, it works as a great base layer underneath my ski jacket. Totally versatile! I’ve had other base layer products but nothing near as good as this. I’m 5’8” and about 150lbs and 30” waist and the medium is a perfect fit. Very comfortable and form fitting and keeps me dry when in the snowy conditions. I’m so happy with this purchase. The thumb hole and watch slit are great features. Another high quality product by De Soto!!

Polypro thermal top

This is my second top in 3 years. First one is still like new. The sale was too good to pass on another one. I find this top to be very warm... it’s my go to for running in 20 degree weather or below. It’s too warm above that. I also wear it Nordic skiing and fat bike as mid layer. I am 6’ and 160 with 30 waist and 40 chest.... medium fits perfect.

Warm and comfortable

It was smaller and tighter than expected, but it felt great.

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.
