Originally designed for the French Navy, and later made famous by the likes of James Dean, Pablo Picasso, and JFK. What makes the Aviator Breton better than the rest? Ours is made with 98% Merino Wool from New Zealand and 2% spandex. This means you can wear it for several days before it needs to be washed. Merino wool is antimicrobial by nature, and refuses to hold an odor. Thoughtfully designed with style and comfort, so you can wear more and pack less.
