Under Armour Men's Castlerock Grey ColdGear Infrared Shield 20 Jacket

The Under Armour Men's ColdGear Infrared Shield 2.0 Jacket in Castlerock Grey is a cold-weather outerwear essential designed for active professionals and teams who need reliable protection without giving up freedom of movement. Built from 100% polyester, this jacket combines advanced material technology with a refined, streamlined fit to handle demanding outdoor conditions.

UA Storm technology forms the first layer of defense, treating the outer fabric to repel rain and moisture without adding weight or blocking breathability. Beneath that, the bonded 3-layer softshell construction provides durability and structure while maintaining a noticeably quiet outer layer.

The material resists wind from all directions, keeping cold air out during commutes, work sites, or athletic activity. The real star of this jacket is the ColdGear Infrared lining. Under Armour applies a soft, thermo-conductive coating to the interior that absorbs your natural body heat and continuously radiates it back, keeping you warm without adding bulk.

This is not standard insulation. It works with your body rather than simply trapping air, which means consistent warmth whether you are moving or stationary. Four-way stretch construction ensures the jacket moves naturally in every direction, so reaching, bending, and layering over other garments stays throughout the day. The fit is streamlined.

Not too tight, not too loose. Secure zip hand pockets and a chest pocket keep essentials organized, and a drawcord hem adjustment lets you seal out wind for a custom fit. Castlerock Grey is a versatile neutral that works across a wide range of uniform and branded apparel programs.
