I bought one for myself and another one for a present because i liked it so much. It is lightweight, but still keeps you warm. Its got a good band around the bottom of the sleve that doesn't stretch out.
"A great top or middle layer for work or play."
This MH Microchill Zip has been a great outside or middle layer for mild to cool conditions. The Medium fits nicely for 6'2", 170, although the arms could be a little longer. It's soft to the touch and wears well so far. The zip is always a convenient way to dump heat when needed. I would definately purchase again.
