5oz Cotton Linen Open Collar Short Sleeve Shirt IHSH-447-SAX - Sax Blue

The Iron Heart IHSH-447-SAX 5oz Cotton Linen Open Collar Short Sleeve Shirt in Sax Blue is available at Rugged Gentlemen Shoppe with fast local shipping and easy returns. As Iron Heart garments are produced in limited quantities, availability can vary across retailers once certain sizes sell out.

Similar in fit to our mechanic shirt cut, this short-sleeved summer shirt is made from a lightweight 5oz cloth, blended from 80% cotton and 20% linen. This creates a garment that feels soft, floaty and highly breathable — perfect for warmer climates. While it shares features with our mechanic cut — including a straight hem and split seam gussets — this is a unique cut in its own right, featuring four-hole buttons with horizontal placket holes for a more secure fastening, action pleated shoulders and a button and loop fastening at the collar. Finishing touches include a chainstitched embroidered Iron Heart chest logo, and yellow internal bobbin thread for a splash of summer colour.

Our Fit Notes

Mechanic-style shirts typically feature a practical, workwear-inspired cut with a comfortable fit through the body and sleeves. They are designed with durability and everyday wear in mind.
