Professional Solid Black Appearance

The solid black color provides a sharp, authoritative, and professional look, making it the top choice for police, SWAT, and elite security units worldwide. It allows for easy integration with existing tactical gear and maintains a uniform appearance for team cohesion.

Advanced G4 Ventilation System

Based on the G4 (Generation 4) combat apparel platform, this shirt is designed for maximum cooling. The torso is constructed from two distinct high-performance fabrics: a soft, moisture-wicking material on the upper chest and a durable, highly ventilated mesh fabric on the lower torso and back, dramatically increasing airflow and comfort.

Full Tactical Functionality

Engineered for mission efficiency, the shirt includes zippered arm pockets on both short sleeves with large velcro panels for attaching department insignia and IFF markers. The professional quarter-zip stand-up collar offers neck protection and adjustable ventilation, making it adaptable to various operational conditions.

Durable, Performance-Oriented Construction

The sleeves and shoulders are made from a rugged, lightweight Polyester/Cotton rip-stop fabric to withstand abrasion from slings and gear. The entire shirt is constructed with high-quality stitching, including a locking process at the hem to prevent fraying and ensure a long service life through rigorous use.

Every detail of this G4 combat shirt can be customized—from the precise fabric blends and weight (from 160gsm to 350gsm+) to the pocket configuration—to ensure 100% compliance with your agency’s specific tender requirements.
