As I've gotten through one winter with these, I am beyond delighted. They are so comfortable, not spare in the cut like so many other brands nowadays trying to make a few extra pennies skimping on the material. I have them in grey in a larger (lovely and baggier!) size for pajama use, and I bought these blue ones normal sized for wearing under jeans on colder days. The blue ones are a slightly different fabric consistency -- a little lighter in weight -- than the heather grey. This is better for layering I think. Long Johns can have you overheating pretty fast if they're too thick. (I am equally pleased with the matching tees I bought for these too.) One teensy flaw in the pants is that they should be a little more accommodating over the backside. Consequently, it felt at first like the waistband was creeping down in the rear. Fortunately I got used to this, because ever since the dum-dums in Fruit of the Loom discontinued the great, sensibly cut thermals I got from them it must be more than ten years ago, I have not found suitable replacements until this Comfort Choice brand came along. At last I've been able to throw the tattered ancients away.
