Too soon
Apparantly this was to be a Christmas present from my wife...thanks for spoiling the surprise on 12/21.

Great quality bag, but still a little chilly for me...
This is a beautifully well-made quality bag that was tremendously comfortable to sleep in. Two caveats, the drawstring is a little bit cheap feeling and easy to get tangled in. That being said, I have no idea how it would be modified without adding weight. Additionally, I was cold when it dropped down to freezing, and was fully clothed with multiple layers and down pants/jacket. I still gave the bag 5 stars because I think this is an individual variation and simply something to be aware of for those individuals who run VERY COLD at night.

Warm bag
Just used for two night in mid 30 degree. Bag was warm but not too hot for the temps. Very lightweight. Is a little hard to put into stuff sack.

new sleeping bag
I have not used the bag on a trip so my feedback is initial. Would be nice to have pocket to hold phone to keep it warm in bag.

Fethered Friends sleeping bag
Certainly the best sleeping bag I ever had. Very light and warm. Great quality.
