SoffeMJ Soffe Men's Core Undershirt T-Shirts (3 Pack)

Are the sleeves fitted or do they flare out? The ones I was issued were fitted but I've seen some as of late that are flared.

Do the sleeves on these T's have a large diameter - that is sleeves made for people with tree trunks for arms?

Are these Tshirts cut long? After long term use how bad do they shrink?

When will the mediums be back in stock?
