perfect cotton/polyester combination for light summer lounge/sleep pants; kind of parachute material, like cargo shorts I had years ago.  I love them, ordered more, just in case the price went up later (don't raise the price, please).  They wash perfectly, but let them air dry, no dryer, which doesn't take long.
My only complaint, only 2 patterns; I am not really a plaid person, love the checks, but hope they introduce more patterns/colors, stripes, etc.  thanks for a great product!
