We had an Ultralite Super for my wife. Great bag -- very well made, plenty of loft, beautiful construction -- just a wonderful bag.

Just be aware that it's a very narrowly cut mummy bag. Though she is quite thin, she likes to thrash around a lot while sleeping. So we sold it and bought a Montbell bag, which also has a full zipper, but the stretchy design lets her move around a lot more.
