The Grundens Balder Bib Pants are cut to enhance mobility while improving mechanical ventilation. This prevents overheating during strenuous activity. The width adjustment with snap button makes it easy to create a custom fit. The construction of these bibs features a solid upper panel, heavy duty eyelets for attachment of fishing tools, roomy inside security pocket, and reinforced leg cuffs. These bibs are made with a new suspender/buckle design that prevents unintended release while making it easier to dress for action.
