M-43 Overshirt

Story

Modernized WWII overshirt cut and sewn from breathable linen

Based on a classic WWII military silhouette, the M43 Overshirt is built for year-round versatility, transitioning easily from a cold-weather mid-layer to a lightweight standalone jacket. It is cut from a substantial linen that provides an exceptionally soft drape right out of the box and will continue to age gracefully with heavy wear. Vintage-inspired details like replica thirteen-star shank buttons honor the garment's historical roots while keeping the profile sharp for everyday use.

Features

• Generous armhole and sleeve allow for easy movement and comfortable layering
• Button-adjustable cuffs provide a customized fit at the wrist
• Two large pleated chest pockets offer ample storage for daily essentials
• Authentic replica thirteen-star shanks nod to classic military hardware
