High-insulation fleece jacket designed for cold-weather use, layering systems, and extended wear in both operational and everyday environments. Can function standalone or as part of a layering system.
Built from high-volume polyester fleece, the AJAX 2.5 delivers substantial warmth while maintaining breathability and freedom of movement.
The updated 2.5 version adopts a streamlined unicolor design, making it easier to integrate into professional, military, law enforcement, and security environments where contrasting color panels may fall outside uniform regulations.
Why It Works
High warmth-to-weight performance
The 385GSM high-volume fleece construction provides significant insulation without the bulk commonly associated with heavier cold-weather garments. The result is a jacket that remains comfortable for extended wear while delivering dependable thermal performance.
Designed for active cold-weather use
A high CLO insulation value helps retain body heat during low temperatures, while the breathable polyester construction assists with moisture management during movement, reducing overheating compared to less breathable insulating layers.
Professional unicolor configuration
The AJAX 2.5 replaces the contrasting panel design of previous generations with a clean monochromatic appearance. This allows easier integration into military, law enforcement, security, and professional environments where uniform compliance and reduced visual signature are important considerations.
Built for standalone or layered systems
Warm enough to function as an outer layer in cool conditions while remaining low-profile enough to integrate into larger cold-weather clothing systems when temperatures drop further. Compatible with our MJC® system.
Comfort during prolonged wear
Flatlock seam construction reduces friction points and improves comfort when worn beneath load-bearing equipment, backpacks, or outer shells.
