The Metal Mulisha Murk Custom Sherpa Fleece Hoodie is the heaviest and warmest hoodie we make, built from the ground up with a custom fit to match our more relaxed fit heavyweight hoodies but in a super heavy sherpa fleece. You can feel the weight, warmth and quality when you slide on the 14 oz (400 gm) fleece with sherpa lining on the arms, body and hood. This thing is sick.
