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

Iron Heart's ultra heavy flannel (UHF) shirts are the essence of their brand: tough, sturdy, yet incredibly comfortable. Woven with Aspero cotton from the Andes, the 12oz fabric is double brushed on the inside and single brushed on the outside, creating a plush, warm, and windproof flannel. This work shirt is a must-have in any wardrobe, especially in navy with wabash-inspired chalk stripes. For FW24, they've stepped up the game and upgraded to four-hole buttons for a stronger hold.
