This is an authentic U.S. ARMY OG-107 Utility Shirt. I purchased it in near deadstock condition, and I have only tried it on myself and have not used it outdoors. It has almost no signs of wear and is in excellent condition. This model was adopted in the 1960s-70s. While it has a rugged military design, it is simple and easy to incorporate into current styles. It pairs well with denim and slacks, and is also useful for everyday wear. ⸻ [Size Tag] 14 1/2 × 33 (Equivalent to M, a size that fits Japanese people well) [Actual Measurements (laid flat)] ・Shoulder width: 41cm ・Body width: 51cm (underarms) ・Sleeve length: 64cm (from shoulder) ・Length: 74cm (from collar to hem) *Please allow for slight errors. ⸻ [Condition] ・Purchased in near deadstock condition ・Tried on only by myself ・No noticeable stains, damage, or fading ・Good stiffness of fabric and color retention ⸻ [Additional Information] ・Authentic item with NSN (National Stock Number) ・Open collar gives it a good look even when worn alone ・Recommended for military/vintage enthusiasts Immediate purchase is welcome.
