The good people at the Boston-based menswear shop Ball & Buck are giving away one pair of Randolph Engineering sunglasses! This giveaway actually coincides with one of my current obsessions: The Randolph Engineering P3 (photo above), the round-lensed US Navy standard issue submarine sunglasses. I'm not sure why one would need sunglasses while working/operating a submarine, but I'm sure the Navy has it all figured out. The P3s are classics, yet unexpected—a combo that's hard to beat in my book. All that said, the winner of this giveaway will be able to choose any of the RE styles that Ball & Buck carries (up to a $179 value) like their famous military aviators as seen on these guys.To enter the giveaway: Like Ball & Buck on Facebook and leave a comment below. The winner will be chosen Monday and announced on Facebook and here. Good luck, these are the perfect late summer shades!

The winner is Catriona! Congratulations!
