Minimalist design and durable, high-quality materials are the driving forces behind the Oakley Barrelhouse eyeglasses for men. The sleek, full-rim frames consist of C-5 alloy, a lightweight material that boasts durability, shock absorption, and scratch resistance. Bayonet temples latch on to the rims with integrated spring hinges, and Unobtanium temple tips increase their grip as you perspire for less slipping. Air-filled nose pads adjust for a custom, comfortable fit. With rectangular frames, the architecture of these full-rim Oakley eyeglasses adds definition to the features of oval, round, square, and heart-shaped faces.
