    • little pricey

      For the price, I hope they last a long time.. I have washed them many times and they seem to be well made. No piling or wrinkling. Also very comfortable. I use them as pajama bottoms too.They do keep me very warm, especially riding my motorcycle. I will get the top when on sale.
