The Proof Hat is a traditional beanie with graphic modern texture. The tubular double-ribbed brim flows into a motif of crisscrossing forked ribs. Channels of cartridge rib add a second layer of deep texture to create a striking unisex cap. Pair this satisfying knit with the Proof Scarf for a matched set or work up a bevy of hats to try out all the shades of Arbor or Dapple that speak to you.
