Trench coat.

Its signature features include a double-breasted front, epaulettes and a belt (the original styles had D-rings to carry flasks, maps and grenades on), while it is constructed from a tightly woven cotton fabric, the fibres of which are waterproofed before being woven, which gives it its lightweight handle.

Its timeless style and functionality have earned it a place in the annals of great menswear design, and it remains an essential winter garment to this day.
