The RefrigiWear Insulated Softshell Bib Overalls are comfortable, soft and durable while still providing industrial-grade warmth. The overalls are wind-tight, water-repellent and fit snugly but never tight. Insulated with 7.5 oz. synthetic down, the overalls feature a super-soft sateen reflective lining that helps reflect body heat to create extra warmth. Front and side zippers make getting dressed easy and provide extra ventilation when needed. Rugged scuff-resistant knee patches and removable heavy-duty Y-back suspenders add durability, and reinforced hand warmer pockets and a zippered front pocket provide extra storage.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.
