JCPenney Foundry equivalent?

I used to love getting shirts from JCPenney's in-house Foundry brand, but they shuttered the majority of it over the past couple years and I haven't been able to find anything similar. I would prefer to stray away from stuff like DXL, KingSize, etc.- more "normal" brands, if that makes sense.

For reference I'm 5'7 and 300ish and typically wear a 3XL / 3XLT shirt.
