The Flat Head 10oz Indigo Wabash Workshirt

Size Guide
The king of fabrication is back!

Many who had the chance to experience TFH's signature fabrics know that they're something seriously special.

This 10oz Wabash fabric is slowly woven exclusively by TFH using denim vintage machines, unlike some other brands that use typical machines. This yields a beautifully textured surface which will gain rich contrast with wear. The deep grand indigo dyed threads will slowly reveal more shades of indigo and gain a stronger vertical texture.

In classic Wabash style, the dotted pattern has been discharged printed and will gradually fade to a lighter, irregular look in areas of wear. Peep the hidden selvage ID on the inner placket and bottom side hems!

Using a single needle and chain stitch construction, this work shirt is extra durable for your daily use! The classic worker style chest pocket designs are elegantly shaped and perfect for your keys or zippo.

When things get cold, you can always use the chin strap collar to keep cosy.
