This shirt is a vintage item that I'd guess was manufactured in the 1990s. It was made in Canada and is in excellent vintage condition, with no major flaws. The material feels like lightweight chambray. This item is 100% authentic.

The shirt fits like a spacious modern men's size large. Here's a sizing chart for reference:

Chest width (pit to pit)- 26.5 inches (67.5 cm)

Length- 33.5 inches (85 cm)

Shoulder width- 20.25 inches (51.5 cm)

Sleeve length (from the shoulder)- 23 inches (58.5 cm)
