This ad for JB Sport Trunks by Coopers has me chuckling a little bit. The advertisement is from 1937. Get masculinized!
You don't have to 'watch-out' for yourself in JB Coopers sport trunks, they 'watch out' for you. You can dive, swim, 'ride the board', scale the mast or lie in the sun without worrying about exposure. That's because of the support built right into the trunks. JBs guard you well, eliminate bulges and prevent disarray.
You look as well groomed and poised in a JB sport Trunk as you do in your finest tailored suit. And you actually gain freedom of action. Your comfort, too, is assured by the masculinized Jockey construction.
The JB Sport Trunk provides masculine and abdominal support. Jockey inner garment of Durene, Bellin inner waistband of Lastex. It is a posture garment, smoothing the contours, controlling the waist. The trunk fabric itself does not cling to your body.
You can't know perfect swim comfort until you've tried JB Sport Trunks by Coopers - either the wool trunk $2.95 or the gabardine $2.50. Ideal for swimming, sailing, sunning, tennis, bicycling, gymnasium and track work. Try them today, and really let yourself go!
