Spiritus Systems builds gear around what operators actually need. Their first piece of apparel is no different. The Mission Rugby Shirt is a flame-resistant tactical base layer engineered for people who wear plate carriers and chest rigs and need a shirt that performs under pressure.
Available at Geartown in both short and long sleeve, shipped fast from the Netherlands across Europe.
Mission Rugby Shirt – Short Sleeve
The short sleeve is built from inherently flame-resistant fabric, certified to ASTM D6413. Not a coating that washes out: the FR protection is woven into the fabric and lasts the full life of the garment.
Shoulder seams are eliminated to remove friction at the exact contact points where plate carriers and packs apply the most pressure. Gusseted underarms provide full range of motion without the shirt riding up or pulling. The extended rugby collar protects the neck from chafing under armor, which is exactly where standard base layers consistently fail.
Silver ion odor control, moisture wicking, and quick-dry performance keep you functional under heavy load. The shirt holds its shape after extended use.
Available in: Multicam, Ranger Green, Black, Tan, Red | Sizes: S through 2XL

Mission Rugby Shirt – Long Sleeve
Everything that made the short sleeve work, now in a long sleeve. Same FR certification, same moisture management and odor control. The long sleeve adds adjustable hook-and-loop cuffs that let you seal the sleeves or fold them back depending on conditions. Works as a standalone top or layered under a wind layer or carrier.
For operators working in variable conditions or needing more coverage, this is the obvious choice.
