Stearns Announces New Anti-Exposure 'Work Coverall' Stearns Manufacturing Com- pany of Saint Cloud, Minn., has announced a new and improved anti-exposure "Work Coverall," Stearns Model #IFS-580. This con- stant wear industrial flotation cov- erall is said to be ideal for com- mercial fishermen, offshore rig personnel, construction personnel and any other industrial employee who must work on, or near, cold water for extended periods. Personnel using these suits are frequently in a kneeling or sitting position on rough decks and sur- faces, thus causing premature wear on the knee and seat areas of the coverall. Stearns has added double layering of fabric to the knee and seat areas of their standard Model #IFS-580 "Work Suit" to extend the useful life of the suit.
