Iron Heart IHSH-402-NAV 12oz Ultra Heavy Flannel Chalk Stripe Work Shirt Navy

About this product

To a great extent, Iron Heart's ultra heavy flannel (UHF) shirts define the brand: heavy, rugged, but amazingly wearable. The 12oz fabric is woven with Aspero cotton from the foothills of the Andes mountains. It is double brushed on the inside and single brushed on the outside, resulting in a very soft yet substantial, thick, warm and windproof flannel. This shirt is a wardrobe staple - seen here in their work shirt cut in navy with woven wabash-inspired chalk stripes.

Made in Japan
