Pieces built around the specific mechanics of getting to work: a bag strap on a shoulder, a leg over a saddle, a body that is cold at the start and warm at the end.
Twenty-six minutes each way is the most demanding wear test we have.
It contains almost every problem clothing has to solve: temperature swings, weather, movement, abrasion at the shoulder, and the requirement to look composed on arrival. Design for the commute and the rest of the day takes care of itself.
