FWI out of Miami makes the only 100% Wool Standard Tux pant I will buy. Our customers love this pant. It is properly cut through the hip area. The waistband will not roll or pull out of shape. The side rails (where the pant adjusts the waist size) are the best I've seen.
I like the straight leg--it gives a nice, long look. This generously cut, well made trouser is a must have basic. Don't settle for less.
