Sawatch 15°F Quilt

Echoing comments that I have not found the enlightened equipment quilt ratings to be accurate. I used to carry a 0° EE, now I carry a 15° katabatic and I'm much more comfortable, even down to temps near or below freezing. Add a warmer pad, and make sure your neck is covered by a buff or your jacket is zipped up to your chin with the hood up and you should be good to go. If you're a woman it's always worth having your thyroid checked too, especially if you are abnormally cold in other situations as well.

A Katabatic quilt and the Rei Flash 55 would be next to pick up. You won’t need the switchback much, the Neoloft is plenty warm and durable.

As others have said, the Katabatic is the choice. However the Katabatic is comfort rated, so an EE 20 is like a 30 deg Palisade. I am not familiar with PCT temps but you may be able to get away with a Palisade. I sleep warm to 20 on a CCF pad.

I love my Katabatic quilt. Extremely light, can open up and breath in warmer hunts and definitely warm enough sub-freezing when buttoned up. Been using it for 5 years on Colorado hunts, all kinds of conditions.

There isn’t really an absolute best, but I like Katabatic for a quilt and western mountaineering or feathered friends for a bag. I prefer quilts down to around the low 20s, bags below that. Having a pocket in your quilt for a sleeping pad seems silly to me.

I love my Katabatic quilt!

Seconding the quilt recommendation. I have a Katabatic that I've had for 6 years or so and it's a real game changer over a mummy bag.
