The Cotton Mill Flex Bib is a non-insulated, traditional hunting bib that’s a favorite among hunters. Constructed from a Cotton/Poly/Spandex blended material, they are light enough for warm weather, yet solid enough to keep you comfortable in cooler temps with proper layering. From chasing longbeards in the Spring to whitetails in the Fall, you'll enjoy the versatility that these bibs offer. The durable material now features a stretch fabric for extra comfort and mobility in any position. Double layered fabric was added to the knees for extra durability for kneeling, crawling, and walking through brush.
