These are my second CW-X purchase. Love my regular cw-x tights, so wanted some for winter. Fantastic! They are plenty warm. So far I have worn them to -3 and had no cold issues. I imagine if I wore an under layer, they would be good to much colder.
I am a firm believer in compression garments, and cw-x’s line are the best. I often combine these with compression socks and have seen noticable difference in my recovery time.
That being said, the compression in the winter tights is a little less than in their normal ones. This is understandable because of the extra thermal material.
The price is a little hefty for a normal thermal legging, but the compression is definetely worth the extra dough in my books!
