Japanese Military Overshirt

Story

A Japanese-made tribute to the iconic 1943 fatigue jacket

With every piece made in Japan from start to finish, Flint and Tinder’s Japan Reserve Capsule reimagines American classics through the lens of Japanese craftsmanship. Ever since our Head Designer, Nick Kemp, flipped through Japanese vintage clothing magazines early in his career, he’s been inspired by the idea of wabi-sabi—finding beauty in simplicity, and honoring the imperfections that come with age.

This Military Overshirt takes its cues from the legendary U.S. Army M-43 silhouette, rebuilt from start to finish in Japan using premium military sateen. Every detail honors the 1943 original while elevating the construction for the modern day. From the double-reinforced stitching to the authentic reverse sateen fabric, this small-batch piece balances rugged utility with refined Japanese tailoring. It’s a versatile, mid-weight layer that feels lived-in from the first wear but is tough enough to become a permanent fixture in your rotation.

Features

• Made in Japan from military sateen for a substantial, durable feel
• Signature bellows chest pockets with custom laurel leaf shank buttons for secure storage

How to Measure - Chest: Measure straight across from edge to edge, starting 1" below the armhole, multiply by 2 - Shoulder: Measure straight across from shoulder seam to shoulder seam. Again, it’s easiest to measure across the back of the garment - Body Length: Start at the top of the shoulder where it meets the neck seam, and measure straight down to the hem - Sleeve Length: Start at the center of the back of the neck, measure straight across to the shoulder seam, and then follow the edge of the garment to the cuff. Pro tip: it’s easiest to measure across the back of the sleeve
