overall I'm super happy with the quality of the product.
Great lightweight material, the light grey color is exactly what you'd expect - should be ideal for layering w/ a button down or sweet, deep-V
It came fairly quickly way sooner than the 'expected delivery date') so I was pleasantly surprised.

Like other reviewers, size was an issue- even after reading all the other reviews and tips about the sizing it still didn't quite work out for me.

I'm 5'7 about 155 lbs., roughly 36 in chest so I ordered the US-M based on research, prodcut description and reviewrs.

When I put it on though it was still a little smaller than I would have anticipated.
I like a slim cut, as this helps to avoid looking like I'm wearing my dad's old hand-me-downs and am too poor to afford my own digs.
The issue for me was in the lenth: that it sits pretty high above the waist and was a little too snug, even for a slim fit cut.

Additionally the arms are quite long, which I suspect wont' be an issue if you wear the sleeves rolled up - it's nothing that a tailor couldn't fix for under $10 if it turns out to be a big issue.
I exchanged for the L and am awaiting that one.  Will hopefully update once I receive.

Even with the extra shipping ($5), potential visit to a tailor ($10), for under $40 this is still a good product at a very reasonable price. Try finding that at any decent 'mall store' or local clothier - it won't happen.
