Comments about Altamont Line Diagram Theory T-Shirt:
I bought this for my math gifted son as a present. The shirt looks and feels great. The only issue is that it is slim fit which wasn't stated. He normally wears a regular fit medium. I let my other son try it on since he normally wears slim fit. It appeared to fit more like small so order a size larger than normal.
