MACKINAW WOOL BIBS HERITAGE30 This 2"-wide cotton webbing strapFilson wool bibs have kept outdoorsmen warm in freezing conditions for three decades. The thick 24 oz. wool is made from only the longest, strongest fleece fibers, with no synthetics blended in. Tightly spun yarns are woven into a dense twill that resists water and wear, while remaining highly breathable. Our Mackinaw Wool can absorb up to 30% of its weight in water without feeling damp or clammy, and will maintain its insulating power even when wet.
