The newest addition to our GrizzlyTec^® collection, Rigor is the hardest working vest in the business, hands down. It is a heat-retaining, abrasion resistant, windproof, and water resistant vest, all without adding extra, bulky weight. Combining rugged utility with timeless style and versatility, Rigor acts as a warm inner layer—and effectively holds its own as a durable and protective outer layer. Cozy snowtop poly sherpa at the collar and yoke, reflective trim, and a handy cell phone pocket at the chest give this innovative vest added comfort and functionality. The Rigor work vest is the ideal, all-season vest you'll reach for darn near every day.
