Duckworth Men's Maverick Long Sleeve Crew

A men's long sleeve crew base layer made of 100% Montana merino wool in a 160 gsm fabric, for wearing under other layers on cold winter days. Duckworth says the wool's natural crimp gives it stretch, and that it is moisture-wicking, soft, no-itch and odor-resistant. It comes in multiple colors and should be hand washed cold and dried flat. The product page calls it "American-made with Montana wool," and Duckworth's wool page says "Made in USA."
