In reply to CharlesE: Poppers + Gloves is an awkward couple.
Also do not underestimate the importance of design for a belay jacket. There is a local company here that does the most amazing, perfectly stitched, custom sized, choice of fabrics (etc etc) down sleeping bags. Decent prices as well (two months minimum waiting list though). They also sell two types of (again, excellent quality) down jackets. Nobody buys them. Why ? "They do not look good" is everybody's answer.
Now, you might ask, why would everybody from the lowly trekker to the hardcore mountaineer care for design ? First, at least 50% of the time the belay jacket is worn around town. Second, nobody likes looking like a deformed barrel in their Facebook pictures.
Also do not underestimate the importance of a decent stuff sack. One that can be attached to the harness and does not need an industrial press to get the jacket into.
