How do you engineer an ultra-lightweight jacket to be even lighter? Warmer? More durable? More adventure-worthy? Proof can answer that with just one word: graphene. The thinnest compound ever discovered, weighing in at just one-atom thick, is infused throughout the Moonweight Collection for a lineup of outerwear that’s tough to beat when it comes to warmth-to-weight ratio. Graphene’s high tensile strength means it’s built to take a beating—so just toss it in your bag, and the sky’s the limit.
