You can do it all in the Insulated Diamond Quilted Jacket for men from the RefrigiWear EnduraQuilt Collection. This thing is one tough mother puffer. Long after those box-store work jackets fall apart, the Insulated Diamond Quilted Jacket still has your back with a durable wind-tight, water-repellent outershell and 240g industrial-strength insulation. Sizing Instructions: For the most accurate fit, take your measurements over the base layer of clothing you intend to wear with this RefrigiWear gear (such as thermal underwear, jeans or a sweatshirt) and refer to the size chart for this product.
