I live in Oregon and it dosent get too cold here but it does get humid cold the kind of cold that just creeps up your pant leg. I'm 6'1 200lb and these were the only reasonable pair of xl LONG thermals I could find. Other then carhart at twice the price. I have worn them once and seem fine. They did shrink a little in the was but as expected. I would buy again. Good for work, snowboarding, hiking. If your looking for something that will keep you warm while standing still you might look for something else as these are not to thick but great for activities.
