warm shirt

By: 17 July 2022
I bought this shirt in size small, which for me as a 170cm tall 125lb female is still a bit too big (when folding cuffs it's fine) but that means I can wear layers underneath and at the back it is super long reaching the back of my thighs. I wore this shirt for two weeks as a jacket/over shirt on an outdoor work trip, it is very warm and cozy soft, keeping out the wind as well. Buttons are easy to do up and undo, even with gloves on. Just love it!

Awesome shirt, fits perfectly all round & I don't have to put on layers on the colder days. Highly recommended quality product.
