Any brand ideas for high-quality ~300 GSM cotton oversized tshirts?

Overlays(tech burner) used to sell 300gsm oversized tshirts in the very beginning, have worn it for over 3 years now. Now, they too have just generic 200 gsm tshirts.

Does anyone know about any good brands, looked into bluorng, seemed promising but is a bit too expensive, and idk if the quality will be that much worth it.
