Superior added warmth as a layering vest or an over-the-top shell. This incredible heavy mid-weight 4 layer vest is one of the most versatile pieces in the COS arsenal. We wear this as a layering piece and being sleeveless, this approach obviously assists in keeping bulk in the arms to a minimum. We would be lying if we said this vest didnt end up on our backs while checking cameras and food plots though- its simply a hard one to leave at home. Constructed with Berber- Wool and Fleece-Wool shells in a paneled approach for the ultimate in a warmth / bulk combination. The 40 gram Quiet-Loft insulation compliments the WindSeal-TC3 wind barrier and 3X-Tricot lining perfectly. Full length YKK zipper front, lined side zipped hand pockets, upper side entry chest pocket on wearers left, safety harness vent in the back, and lined collar.
