Half cotton, half linen. Great tensile strength despite light summer weight. Over time a linen tee will stretch, only to snap back after a good wash & dry. You'll appreciate the slight wrinkle common to any linen-blend garment. 

SPECS

50% Linen, 50% Cotton. Fabric imported from Portugal.

American Trench's "factory" for this product is in fact the vertically integrated ecosystem that is the garment district of Los Angeles, where the fabric was knit, cut, sewn, dyed, and washed at small family-owned facilities all with several miles of each other. Made in the USA.
