BUILT TO MOVE.READY FORANYTHING.

Engineered for tactical operations and extreme weather performance, the Expedition Weight Base Layer IV Quarter Zip Top features Envirowear® Layer IV fabric—a durable 8.0 oz expedition-weight fleece designed for serious fieldwork. The brushed inner surface delivers comfort against bare skin while the mesh jersey outer layer accelerates moisture wicking and enables seamless layering under tactical gear.

Built tough for demanding missions, this quarter zip base layer incorporates set-in sleeves and dropped shoulder seams that protect against gear interference while maintaining unrestricted range of motion. Flat seam construction eliminates chafing—critical when wearing body armor, plate carriers, or heavy tactical equipment for extended periods.

Advanced antimicrobial treatment prevents odor buildup and extends fabric lifespan, making this base layer ideal for multi-day operations and training exercises. Superior moisture-wicking technology enables rapid evaporation and quick air drying, keeping operators dry and comfortable in high-output tactical scenarios.
