Vintage Long Sleeve Blue Shirt by Duofold

Here is a super cool vintage long sleeve shirt from the 80s/90s by Duofold. Made in the USA. The outer layer is 55% polyester and 45% wool. The inner layer is 100% Thermax polyester. This gives it a bit of a thermal material vibe, without the usual waffle to the fabric. Dark, royal blue color throughout. It's amazingly soft, warm, and comfy, and it's in excellent condition with years of life left! The tag says Large, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 21"
Shoulder to end of sleeve (including cuff) 27"
Length 29"
