Impressed so Far
I have yet to get this bag out into the backcountry, but on a drive across the country recently I used it while sleeping at a rest area. The temperature in the car got down to about 30 degrees and I was plenty warm. It seems like this bag will be keeping me warm in the future at temperatures even lower than that! I can't overstate the quality and feel of this bag: simply spectacular.

A very good bag. I wanted light and warm. The bag is light, warm and very well built.

Looks purple but is more of blue.

This bag is more blue than it looks in the picture.
This is the only thing I can really add because the bag itself is just amazing. We both already know that. No need to preach to the choir. In the pic, it looks kinda periwinkle. I wanted red but it wasn’t available. Oh well, who cares? Well, it’s actually a super solid, royal blue! Just a gorgeous color! Also it’s amazing, warm, light, yada yada yada. We know! Get the bag.

Great but not perfect
Used the bag 3 times now, it's great but already had a big feather come out and the bag has signs of feathers poking through in multiple places. Love the bag but hoped this wouldn't happen for years not days after owning.
Feathered Friends
Hi Kris, Quills poking through are rare, but they do happen. If you have a feather poking out, do not pull the feather out. While we use >90% down clusters, which have no pointy ends and cannot penetrate fabric, the occasional feather does work its way through fabric or a seam, almost invariably quill end first. If this happens, carefully pull the feather back into your sleeping bag by grasping it from the opposite side of the fabric. Once the feather is back in, massage the area to reposition the quill end of the feather and reseal any puncture in the fabric. Rest assured, a few rogue feathers will not affect the warmth of the sleeping bag. There is a lot down in there. We hope you enjoy! Feathered Friends
