I own several pairs of long bottoms to help get me through Chicago's cold winters, and except for Under Armour's running pants (available at over three times the price of these bottoms), these are far and away my favorites of any I own. They are very reasonably priced, extremely soft and comfortable, and thick enough to keep you warm even on very cold days. I walk my dog frequently on the beach along Lake Michigan throughout the winter, so I have especial need for very warm bottoms, and these definitely fit the bill.

While I still love the Under Amour bottoms, their price is close to prohibitive for daily use. Since I can get three pairs of Duofold bottoms for less than the price of a single Under Armour, but get very nearly the same warmth and comfort, these are definitely going to be the main bottoms that I wear each winter.
