Our Service Jacket returns—still faithful to the P-41 Marine Corps fatigues that inspired it, rebuilt with a high-density Japanese twill. Needless to say, it continues to earn its keep: with deep patch pockets sized for notebooks and essential gear, double-needle stitching, bartacks at stress points, corozo buttons built to last, and a tall collar to protect against wind and weather. We kept what worked. What's changed? The fabric. This iteration features the same yarn-dyed cotton twill from Okayama, Japan—a high-density weave with a crisp hand feel that softens with wear, developing natural creases and color variations over time. The yarn is dyed completely before weaving, ensuring a deeper, more permanent color that ages well. We've started that process with a garment rinse, so your Service Jacket arrives with subtle texture and variation already built in. Cut and sewn in New York City by one of our most trusted garment makers.
