Size l fits well as you can see in my picture. Usually wear xl but for this base layer the large was perfect. I also have the matching base layer pants but in xl size and they are perfect.

It's my first carhartt, never had one before as they tend to be pricey. This is a great base layer/undershirt. I like the little straps that allow you to hold sleeves in place when pulling another shirt over it.

This however, was made for toddlers. This stuff is so sub par it's unbelievable.

Haha this is not warm. A $10 item made in china has better thermal protection that this overrated dish towel. When washing it collects allllllll the lint and static.

After just one wash the elastic in the collar is already starting to fray and pill. There is pilling elsewhere on the shirt too. The elastic around the wrists is pretty weak.
