You may not know it, but EINSTOFFEN was conceived as a traveling brand from the very beginning. Long, long ago, we started ourselves up with a dream and an idea-- to import T-shirts from Bangkok. (Maybe we'll get back to that someday.) Right from the start, we knew a thing or two about traveling from our own backpacking experiences. And so of course we know our customers tend to be the wanderlust type, too. Rule Number 1 for a pair of globetrotting sunglasses? Can not be too fragile. In fact, must be able to withstand... a lot. This design completely lives up to that charge: robust and thick bio-acetate, polarized lenses, and steel pins inside the temples. Get out there.
