of construction.

Boombox hat is an original two colors hat stranded in an op-art style slip stitch pattern knitted top down with a fold-under brim. The stranding combined with the overall slip stitches and the luciousness of malabrigo Sock produce a thick cushy fabric for a warm head under cold conditions.
