The M-Tac Summer Combat Shirt combines high-quality materials, advanced manufacturing technologies, and a thoughtfully designed functional layout. The back and torso of the shirt are made from Polartec Fire Resist knit fabric (modacrylic, lyocell, spandex). The primary component of this fabric is modacrylic — a synthetic fiber known for its flame-resistant properties. Combined with other fibers in the Polartec Fire Resist blend, it offers a unique combination of flame and water resistance, along with softness and elasticity. The sleeves and collar are made from durable NYCO Extreme fabric by Brookwood (nylon and cotton). This lightweight American-made material is approximately three times stronger, ten times more breathable, and dries significantly faster than standard NYCO fabric. To improve breathability and moisture-wicking, the brand’s designers have added mesh panels under the arms. The sleeves also feature vertical zippered pockets with protective flaps for storing valuables. The Velcro panels are equipped with special slots for glow sticks and writing tools, and there are additional pen pockets on the left sleeve. This tactical shirt significantly enhances comfort and thermoregulation when worn under body armor or load-bearing systems. The model is suitable for use in both warm and cool weather, making it a versatile choice for demanding environments.
