Wow.., these two-piece sets are made of the softest 100% cotton broadcloth, with a long-sleeve pullover shirt, and a pair of long pants with button adjustments at the waist, small of the back, and at the ankles—to seal ‘em off. Not meant for us middle-aged (or older) mid-riffed men, but the more fit and trim ones! We got the largest size, which is about a 34” waist. If you fit, there’s nothing finer! 16 oz
