Designed expressly for and with Gretchen Bleiler, the GB Signature gloves are as dedicated to warmth, comfort, and durability as they are to style. The Membra-therm Plus membrane is sure to keep you dry and the PrimaLoft insulation makes any day on the mountain toasty warm. The GB shell is a rich and rugged combination of Pittard's leather, a reinforced palm, and herringbone performance fabric...built to withstand all the hits you can give it.
