We call these Essence—once you slip these on, you’ll understand why: these casual-cool glasses for men will be the heart of any outfit as they are equally appropriate for days at the office or nights on the town. Essence has a keyhole bridge and all-around thick temples. Its frame feels firm and durable, as it's constructed in biodegradable acetate. As for its frame shape, its medium-fit and rectangular structure is meant to enhance those who have square, oval, and heart-shaped faces. Choose the style in one of three colours: warm Havana, classic (and smooth-to-the-touch) Black Matte, or Mocha Tort, a speckled acetate in chocolatey-brown.
