Here are some Sears Catalog ‘Speed Suit’ pages we found online. Also called Leisure Jumpsuits and Putter Suits, these short sleeve, one-piece suits are ideal for household and yard chores or leisure wear in warm weather. The suits boast such details as two pleated chest pockets and Perma-Prest sewn in leg crease and wide spread collar. The special polyester and cotton weave actually ‘breathes’ for comfort. Speed suits ranged from $10 to $30 in Sears The Men’s Store.
“What is a speed suit? Only the perfect habilitant for the science minded man, who knows both comfort and ease and demands them from his clothing. In a speed suit you say to the world: ‘Look out! I know what I’m wearing for the rest of my life!'” — Dr. Venture
