HELIX HYBRID • Archean Black

Size: I (XS / EU 42-44)

Elevated yet casual, blazer-jacket hybrid, fine-tuned to balance sophistication with effortlessness. 

The unique construction is unlined, keeping it cool and feather light.  The extended facing doubles up the shoulder with precisely fused segments that create just the right rigidity at the shoulders, resulting in a jacket that can be packed in a bag, worn casually in the neighborhood, and dressed up for evening outings.  The collar is engineered to be worn both upright or rolled back.

This fabrication is an exceptional cotton-linen jacquard from a century-old Japanese mill and exhibits a weave that eludes definition, being both refined yet subtly raw with texture that resembles leather or bark.  

Exquisite bias tape seam finishing  |  Water buffalo horn cuff buttons (hidden by placket)  |  3 nearly invisible hook & eyes for a clean, flush closure
