The Iron-Tuff Low Bib Overall is great for high activity in sub-zero temperatures. A high back provides extra warmth for internal organs. Adjustable, heavy-duty 2" elastic suspenders have a back yoke to prevent them from slipping off your shoulders. Thigh length, heavy duty leg zippers with storm flaps make it easy to slip on over boots, and a heel reinforcement patch prevents tearing. This bib has a low front, making them ideal for women and also for high activity. Large insulated pockets provide extra storage.
