Highland ERDL Camo Crewneck Sweatshirt

The Highland ERDL Camo Crewneck Sweatshirt showcases one of the most influential camouflage patterns in U.S. military history. Featuring the brown-dominant Highland ERDL pattern across the entire garment and the American Heritage Museum logo on the left sleeve, this sweatshirt honors a design that helped shape modern American combat uniforms.

ERDL - short for Engineer Research and Development Laboratory - was developed in the late 1940s and refined for combat use during the Vietnam War. It marked a shift from solid-color uniforms to disruptive camouflage designed specifically for jungle and varied terrain environments. Two primary variants emerged in Southeast Asia: the greener “Lowland” version for dense jungle and the more brown-toned “Highland” version for drier terrain and mixed vegetation. ERDL would later directly influence the M81 Woodland camouflage pattern adopted by U.S. forces in the 1980s, cementing its place in camouflage evolution.

This all-over print crewneck brings that historic pattern to life with seamless, edge-to-edge printing - no white lines at the seams. Made from 100% polyester fleece, it delivers reliable warmth with a smooth, medium-weight feel. The classic crew neck and set-in sleeves provide a comfortable, timeless fit, while the custom cut-and-sewn construction ensures a clean, finished look throughout.

Assembled in the USA from globally sourced parts, the Highland ERDL Crewneck blends Vietnam-era camouflage heritage with modern comfort and durability.
