Simple and light!

Haven't used this in the field yet, so I'll just comment on the sizing. I'm 5'8"/150lbs with a 40-inch chest and the Medium fits perfectly with enough room to layer a micropuff-style jacket underneath. Seems to be good quality and fabric. Was looking to add to my UL backpacking arsenal and this might be just the ticket.
