Heavy Polyester in 3Sixteen Denim?

Hey everyone,

I saw this shirt on sale on 3Sixteen, I’m not planning or even able to buy. I’m just curious about the construction.

But what’s the deal with this shirt being khadi denim handloomed in India with it being nearly 70% recycled polyester for 250 retail? It’s beautiful but I don’t understand the construction here, I am not a polyester hater in some circumstances but this is ridiculous to me.

I can’t think of a reason why this would be the case, am I just missing something here?
