Sierra Designs Vestal 20°F Down Sleeping Bag - 600 Fill Power, Long

I bought this and a very similar bag (the vestal rated to 20F). both bags are great and I highly recommend going with down - much, much easier to compress and lighter than my old synthetic. I prefer the vestal for the additional 5 degrees of warmth rating.

My first down bag - warm, roomy, and a piece of cake to compress into the stuff sack - amazingly smaller and warmer than my old north face cat's meow synthetic. Has a number of features not listed in the description: -100% duck down insulation -Full-length, dual-slider zip with draft tube -Pad locks, touch-close chin lock -Includes storage bag and stuff sack -Mummy style I ended up ordering the antero as well (as I wasn't sure of the zipper and pad-locks on this one). Its basically the same sleeping bag as this one (same wieght and uses the same stuff sack) only this one is rated to 20 instead of 25 as it has 2 oz more insulation and is pure duck down vs 80% duck down in antero and this bag has a bit more room (2") in the hips. The antero does have thicker, snag free nylon near the zipper - I prefer the 2 oz extra insulation and will be keeping this one for the slight $ difference

Haven't used it yet so hard to say if it keeps me warm enough. I will say that a white stuff bag is very impractical. Seems strange that it's supposed to be for back packing yet you get a huge white cotton bag to put it in. I would think (and expected) a stuff bag made out of nylon. Can't say yet if I would recommed it.
