Vintage Long Sleeve Blue Thermal Shirt by J.E. Morgan Arctex

Here is a super cool vintage long sleeve shirt from the 80s/90s by J.E. Morgan Arctex. Made in the USA. The outer layer is a 50/50 blend of cotton and polyester. The inner layer is 100% acrylic. Dark blue fabric. 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) 16"
Shoulder to end of sleeve (including cuff) 23"
Length 31"
