31st Engineer Battalion — "We Demonstrate"
Some units don't just serve — they build. The 31st Engineer Battalion has been shaping the battlefield since its activation at Fort Belvoir, Virginia in 1940, earning its motto through decades of combat engineering excellence at Ft. Leonard Wood, Missouri.
This hoodie is built to the same standard.
Crafted from a 50/50 cotton-polyester blend and preshrunk for lasting shape, it carries the weight of history without sacrificing comfort. The front pouch pocket, matching drawstring, and ribbed cuffs deliver the kind of detail that veterans notice. Heavy enough for the cold. Durable enough for the years.
Wear the history. Honor the mission.
