The 2 biggest gripes I had with Thermals over the years was the waistband for my size was too tight so I would have to get a size larger which would fall down and bunch below the waist. Second, the ankle cuff was so tight, no matter what size, you would have to really pull, to the point of stretching it to get it either on or off. The Daresay Men's Thermal Pants fixed both those issues by, finally, incorporating 40% polyester so putting them on the ankle cuff just expands real easy and compresses just as easy for a secure fit and, most of all, the waistband gently hugs the waist snug enough to keep them from falling but, more importantly, loose enough as no to cause any discomfort so I can wear the proper size. Warm as toast, as I wore them out in freezing temps with no problem, and quick drying after washing unlike the 100% cotton ones which take forever. Also they are as soft as the cotton ones with air drying unlike the cotton ones which unless you put them in the dryer they don't retain their softness. Daresay Men's Thermal Pants has figured it out, and just in time for winter, very satisfied with this product.
