Zephron Waterproof Bibs by Black Diamond Waterproof - 1776
Zephron garments provide unsurpassed protection from the elements while being comfortable and durable. The bibs and jackets are nylon coated on both sides by heavy duty neoprene and have vulcanized seams which creates a barrier that water cannot seep through. The bibs have high visibility striping on the upper chest and near the knee to ensure the wearer is more visible.
