The House

Halley & Ko is California surf culture refracted through a Japanese design lens — clean lines, technical fabrics, but cuts and proportions that work on land as well as in the water. The brand is best known for its bonded-jersey surf-to-street pieces that move from a Malibu morning to a Silver Lake evening without changing. Production is split between LA and a small factory in Osaka. The customer overlaps surf, skate, and creative-class — designers, art directors, photographers who live coastal lives.

Halley Brogan & Ko Yamamoto

Halley Brogan grew up surfing in Malibu and Ko Yamamoto grew up skating in Osaka. They met in Tokyo in 2017, moved to LA together in 2019, and founded Halley & Ko in 2020 to merge California surf culture with Japanese street design sensibility.
