The Tactical TopCool Lite is a short-sleeve technical T-shirt made from 100% TopCool polyester, with a fabric weight of 150 g/m² and an overall weight of approximately 190 g. It is designed for those working in hot environments or at a high operational tempo — dynamic shooters, professional operators, hunters — who need a garment that manages sweat without becoming heavy.
The TopCool fabric dries quickly after physical exertion, reducing moisture build-up against the skin. This makes a real difference during a competition day or a day out in open terrain: the shirt stays light and does not cling to the body. The trade-off compared to a cotton shirt is clear — technical polyester wicks moisture more effectively but does not offer the same softness against the skin. For intensive use or as a base layer under a combat shirt, it is the most functional choice.
Two sleeve pockets allow small accessories to be carried — a torch, a field tourniquet — without adding bulk to the torso. Integrated eyewear retainers at the neckline or collar allow glasses to be clipped on when not in use, keeping hands free. The 5 x 8.5 cm Velcro panels on the shoulders or chest allow identification patches to be attached, useful during exercises or team operations.
Key Features
- The TopCool fabric in 100% polyester at 150 g/m² dries quickly, keeping the body dry during prolonged effort.

- The sleeve pockets provide quick access to small accessories without cluttering the torso or interfering with a load-bearing system.

- Available in 6 sizes from S to 3XL, with a chest circumference from 100 cm to 120 cm.
