The new-maker discovery here is NICENESS E. CALDER, NN-1405C18: a Japanese-made, garment-dyed Pima-twill coat with a British military mac reference. Its one-piece collar stand and deep slits accessing trouser pockets are concrete construction details with heritage references.
The official US catalog lists $1,216, black and beige, and sizes S–XL. Fit, exact variant availability, US delivery and returns are unverified, so this is a design profile rather than a purchase recommendation. It is a different product from the brand's CALDER Ventile coat. Exact product
