A further step on from the Type 401 Pleat Pocket Shirt, the Two Birds Shirt creates two pockets with one line of pocket stitching. The pattern is cut with a large front panel pleated into the yoke. Once this is pressed into place, a patch pocket is sewn through all three layers of the pleat. This creates a standard hand-height patch pocket on the outside of the shirt, but its stitch lines also hold the pleat together as a deeper chest pocket, accessed vertically.

The fabric is cut sideways, with no shoulder seam, creating a soft biased shoulder which stretches out and softens as the garment wears in.

The shirt is sewn with all-cotton thread and finished with dyed cotton-covered metal buttons and a Made in USA blue label.
