Combining a lighter weight heritage fabric with the brand's vintage styled mechanic shirt, the IHSH-416-IND is a sturdy spring shirting option. Iron Heart's Wabash fabric, a fabric historically donned by America's rail workers, is woven from rope dyed indigo yarns. After weaving, the dot pattern is meticulously bleached into the fabric, allowing the yarns to fade and evolve with good wear, while the pattern remains bold. The fit of the mechanic's shirt is retro and easygoing, with a comfortable amount of room in the chest. All of the furnishing's of the brand's mechanic shirts are there including snap closures, a straight hem, and side seam gussets.
