My wife told me I have no ass. Her complaint is I'm too skinny. I'm 72 years old and am very active. No amount of food makes me gain weight. At 6 ft. 2 in. 165 lbs. I have what I have. Purchased a pair of these and now I have an ass. Also, I have a sore tail bone and these have helped me when I have to stay sitting for extended periods of time. I ordered size large (as others here have recommended) and they fit just right. Another thing I like is the way they keep my junk inside with no falling out the leg hole. I just ordered 4 more pr. I'm pleased with this product !
