Powell PeraltaRipper T-Shirts

Why do all the reviews of this shirt say it's made poorly and out of thin nylon while your description says 100%cotton?

Is this shirt super soft?

What are the measurements of a medium? Sleeve length, vertical length from neck down? I am 5'9, 150 lbs.

I'm not a skater. i'd kill myself lol! x-d i do love the graphics and 80s skate graphics! is this the real deal?
