This season, END. and 1017 ALYX 9SM partner for the first time, creating a 14-piece capsule that celebrates a technical approach to streetwear. And that’s exactly where this cap sits. It’s coloured in an olive green shade — in favour of Matthew Williams’ go-to black — and has tonal branding embroidered across the front. The back demands the most attention, though — it’s detailed with a reworked, cobalt blue version of that iconic rollercoaster buckle.
