Combining function, fashion, and warmth, the Carhartt Rain Defender Loose Fit MW Insulated Vest is one of our favorite insulated vests out there. The Rain Defender Loose Fit MW Insulated Vest features a nylon fabric treated with Rain Defender DWR treatment for long-lasting water protection. For warmth, the vest is filled with recycled polyester for a high warmth-to-weight ratio and has a Sherpa fleece lining for added warmth and comfort. Zippered hand pockets and a dual-entry utility chest pocket stash our quick-access items, and the interior mesh pockets stash extra layers or gear.
