Man shirt 70% Cotton- 30% Linen made to be comfy. The shape of it is done so you have long sleeve and torso, it comes in ONE SIZE and kinda baggy/large fit so it cover multiple sizes M-L-XL with no problems. The idea is to have a shirt you can use under a jacket if it's cold or as a jacket if it's hot, it's just up to you the result remain the same, you looks cooler.

Washing machine 30-40°, Drier no problem so Iron.

Enjoy it!
