Denim Jac-Shirt - Vintage Black Field Series making it a natural layerLong trusted for work in the West, denim brings weight and structure to this insulated layer. The heavy duty 15 oz. shell blocks cold wind. The body is lined with high pile fleece for warmth, while the sleeves are insulated with quilted polyester to reduce bulk and layer cleanly. Cut like a shirt, it's a straightforward layer that stays warm without feeling oversized. Side seam slits at the hem improve mobility when bending, reaching, or sitting.
