Western Mountaineering UltraLite
I purchased this bag as I found my other high quality down bag -1'C not to warm enough in 4'C temp in my bivy with merinos on. The WM Ultralite was just excellent in the same conditions perhaps even cooler windy temps with a NeoAir under neath.
It's light, compact and fits my 185cm 90kg frame well.

I have a lot of bags...
This is the worst one.
All my bags the temperature rating tends to be conservative, but in this WM bag the rating is hyped.
I am a very warm sleeper, I can do well in most bags even though the temperature has dropped below its recommended use.
Not with WM Ultralight... For the first time I was freezing in a bag that was rated at about the temperature I was in.
WM attempts to create a lighter bag by making the bag smaller and less down filled then other bags. Their specs don't seem to match the actual construction of the bag. I found this bag to be very tight around the shoulders and very cold.
I have bags by Mountain Hardwear, Marmot, Campmor and Western Mountaineering. Either the other manufacturers are very conservative about their own product specs OR Western Mountaineering is way TOO generous on their own specs.
Above all I feel their products are over priced considering these flaws. And I am at a total lose why others gave them a perfect score. Why?

I use a WM Antelope for fall and early winter camping and the UltraLite for everything else. Lightest and warmest 20 degree bag I've ever experienced. At 1lb 12oz and 850 fill, this long version sleeping bag stuffs into the smallest stuff sack for maximum compactness. However I've recently been stuffing it into my day pack with all my other down items and clothes, etc.
This package fits neatly into the bottom of my pack without compressing the down as much as other methods. I don't like using compression stuff sacks for 850 like I used to for 550 and 600. Just a personal thing. I'm 6'3" 185 lbs with plenty of room to spare in the WM UltraLite. No half zip here. Full zip for maximum ventilation and roomy foot box. In my opinion, Western Mountaineering is the "Magnum Opus" of sleeping bag manufacturers!!!
*Highly recommended for people in good mountaineering shape. Not recommended for gorillas!!!

WM makes a great bag. The ultralight series is pretty amazing, makes you feel warm just pulling it from the stuff sack. It keeps me warm at well under the 25 deg rating, huge amounts of loft, and the fabric is surprising water resistent. The outside can get quite damp and the down will be perfectly dry. Even covered with heavy condensation my WM bags have never lost loft.

This incredibly light bag is super warm, and compact. I think it's THE summer bag to own, especially if you usually camp in dry climates. Very solid construction, impecable stitching, box bafflles, draft tube, this bag is well down. In fact it's warm enough to warrant a neck draft tube as well, because you could venture into colder climes with this bag.

Just got mine used and I'm super impressed. So light, well made, a bit tight at five nine, one fifty five. It's my new three-season bag. The Iroquois goes for summer now and the Badger is for colder nights.
