A modular system, developed with Errolson Hugh. An insulating layer and a waterproof layer, worn separately or together — with adjustable down channels across the back that hold or release air to regulate warmth as conditions change. The shell was developed jointly with GORE-TEX: windproof, rainproof, and cut with stretch, with articulated elbows and underarms for range of movement.

ERROLSON HUGH × BOSIDENG
Widely regarded as the godfather of techwear, Errolson Hugh brings three decades of technical design to VERTEX — a collaboration built on how a garment actually performs, not how it looks on a rail.
Performances
Engineered for all-weather protection
Jointly developed with GORETEX : a four-way stretch face fabric with an ePE membrane. Waterproof and windproof, with the give of a softshell.
Shell, down liner, or both together — one jacket that adapts as the season shifts.
Pattern adaptations at the elbow and underarm keep movement unrestricted.
Sourced from higher latitudes where the down grows denser, for warmth without weight.
Angled down channels across the back open or close to adjust warmth, and draw moisture away as you move.
A concealed strap lets you wear the shell over one shoulder indoors, leaving your hands free.
Seamlessly transitions between urban and outdoor settings.
