This hat is named after Porter Square, located on the border of Cambridge and Somerville in Massachusetts. While it’s not really a “square” as much as nearby Harvard Square or Davis Square, it’s got a lot of great restaurants and shops, making it an underrated staple.

In the same vein - though this hat looks simple, it has quickly become a favorite winter accessory. The squishy brim will keep your ears warm, and the stripe detail gives the hat a classic look. With an aran weight yarn, this hat knits up in no time!
