It's hard to find rounded sunglasses that don't look like they are straight out of a thrift shop. But Saturdays Surf NYC, a brand that is always reinventing retro staples, has put a Japanese twist on the iconic vintage frame with a new pair called the Mitsu. The shades, which are handmade in Japan, are named after Mitsu Lowe, a Saturdays brand ambassador and a native of Miyazaki, one of the country's best surf towns. 

"Most of the Saturdays garments are named for close friends of the founders," said Colin Tunstall, who co-founded the brand with Josh Rosen and Morgan Collett. "We wanted a frame that contrasted the original Walker frame, but still had the same classic feel. The Mitsu is a bit thinner and has an oval-shaped lens."

Made of thick plastic, the shades are similar in shape to Oliver People's classic Sir O'Malleys and similar in weight to Persol's PO 649, though these are a bit narrower across the brow. Glass-polarized lenses with anti-reflective coating mean watermen don't have to worry about trading practicality for style. Although they're available in standard black and tortoiseshell, try the Fog – a glassy gray – for something unexpected yet versatile. [$295; saturdaysnyc.com]
