Simply put, Vyper has to be the coolest laptop sleeve. We sandwiched durable, semi-rigid high density foam between a layer of 1682D cross-weave ballistic nylon on the exterior and a super non-scratch lining on the interior – an effective blend. Virtually molded around your 15-inch laptop, Vyper L is the most compact sleeve you can use separately or as additional protection inside another bag… A must-have for every laptop owner!
