These traditional glasses for mountaineers are timeless. We love this vintage look as a piece of history that you may take with you. They have a wonderful steampunk look, yet are lighter weight than a full pair of goggles and offer similar dust protection. This is a traditional mountaineering frame with round lens, a leather nose piece and genuine leather side shields riveted in place. They wear comfortably, yet have hooks on each leg that wrap around your ears and keep them in place.
