Momotaro Heavyweight HBT Flannel Check Workshirt (Red)

Size Guide
That classic design made up to a heavyweight standard!

When you first feel this one in person the amazingly soft cotton flannel is smooth against the skin and keeps you cosy.

Made using vintage weaving machines, the alternating herringbone pattern is woven instead of printed. With time the pattern will maintain it's contrast. The overdyed threads will gradually fade to a softer tone with a soulful look.

Roll up the cuffs when its warm and you can always wear this one as an overshirt on those colder days.

With extra-thick, contrasting urea buttons and diagonal pattern chest pockets, this is a classic choice!
