I purchased these in the red/green/blue plaid for my husband for Christmas and he loves them!  They have held up well in the wash, fit perfectly with room to move and quickly became his favorite cozy pants to wear around the home.  I am not sure about the other reviews that claimed they weren't well made, but the pair I received were fantastic!  In fact they were of a better quality than the ones I had looked at in Department stores at the holidays.  However, it may be because of the specific style/color we purchased.  So when it comes to the red/blue/green plaid ones, I would definitely buy these again!
