Despite a very cheap price as t-shirts go these days, this t-shirt is a nice, heavy-weight, soft cotton blend and the NASA print is nice and thick.  I've washed it a few times so far with no sign of cracking or peeling as lower quality prints are bound to do immediately.

Add that it has my favorite space agency logo so I am dressed for star parties in style.

Bottom Line: I ordered it because of the NASA logo and the price was only $20, so I was really expecting a crappy t-shirt with a not very durable print on it, and what I received is easily worth $30 based on quality of materials and printing.

Also note that they send you a catalog of their other themed products for engineers and astronomers--professional and amateur alike--better than the gift shop at a museum.
