Description
This French Navy blue GAO military shirt is an authentic, brand-new surplus item, identical to the model worn by certain personnel in hot climates. In the field, it makes all the difference: the chest and back remain covered, while the wide-open sides allow for proper airflow during prolonged physical exertion.
Its fabric—65% cotton and 35% polyester—offers a good balance between comfort, durability, and quick-drying properties. In practical terms, whether you’re spending a day at the beach, at the harbor, or on an outdoor construction site, this garment remains more comfortable to wear than one made entirely of synthetic fabric and offers greater resistance to repeated use.
The sleeveless design provides plenty of freedom of movement for the shoulders and arms, which is important for maneuvering, carrying items, or working in extreme heat. What the product description doesn’t show is the increased mobility it provides for repetitive movements; however, it’s best reserved for summer use or environments where full arm protection isn’t necessary.
Easy to care for, this shirt withstands repeated washings without losing its shape quickly. What sets this model apart is its versatility for both casual and active uses: fishing, sailing, light bushcraft, outdoor work, or as a collector’s item with a distinct French military look.
Fabric composition of the military shirt
- Herringbone fabric: 65% cotton / 35% polyester
- New, unworn military surplus
The first thing to check is the fabric if you’re looking for a shirt to wear for a long time in dry or humid conditions. In this case, cotton reduces the rough feel against the skin, and polyester helps the shirt dry faster after sweating or washing—the same practical consideration that applies to its ventilated cut.
Men’s Military Sizes and Equivalents
Sizes follow the French military standard and correspond directly to chest circumference:
- Size 88: bust 88 cm
- Size 96: bust 96 cm
- Size 104: bust 104 cm
- Size 112: bust 112 cm
- Size 120: chest circumference 120 cm
Measure yourself at the widest point of your chest to avoid a shirt that’s too tight when you move. With this type of cut, a proper fit ensures side ventilation without hindering your daily movements.
