The insulator layer. These compact yet warm down filled pieces have been designed in conjunction with the Defender jacket to be worn on colder days when additional warmth is required. Filled with 80/20 Ethical down feather filling, both the jacket and the gilet provide exceptional warmth without compromising on weight. Crafted from quality polyester featuring heat sealed quilting means the superior DWR finish is not compromised by unnecessary external stitching. Features include a two way YKK zip, clean finish elasticated cuffs and microfleece lined zip pockets. Highly compressible, both styles come with a compact pack away bag for convenient storage.
