Guys this is my favorite most comfortable "lazy shirt" it's a different kind of cut that has the seams here in the middle and sides so that the sleeves and part of the shirt are all from the same fabric (it's inside out here so the structure can be seen).

I just noticed it has a hole in it in the front and I'm googling like crazy trying to find the name of this kind of shirt so I can buy another one, it's an old shirt and I can't find it on the brands website anymore. Guys can y'all help me find what it's called so I can find a new one?
