INFLATED HUNTING SUIT HELPS IN STALKING WATER GAME

To enable hunters to approach their quarries in deep water without giving alarm, a buoy that can be inflated with air has been attached to the upper part of a waterproof hunting suit. The wearer can paddle about with his feet, and also have a steady rest for his gun. The bag, when blown up, is about 12 inches in diameter.
