10 degree Swift

10 degree bag and still needed to put on puffy and cold gear leggings. Use a Nemo 5.7 rf rated pad and 1/8 inch foam pad under Nemo. Could be just me.

very comfortable with enough room to move inside. the outer fabric is a bit noisy which will hopefully decrease with use. i also would love a different color. other than that a perfect bag for the 10°f rating with excellent craftmanship.

Nice bag

Very nice bag. This thing is incredibly lightweight and warm. I’m about 6 foot 200lbs. Usually wear a large or XL and the bags a little snug up by the shoulders for me. Set up a tent and slept out side to test it out. Temp only got down to 19 degrees (little disappointing for Alaska in January) but It was toasty warm inside.

Was warm at 18 degrees, no tent, has usual FF high quality

Field tested my Raven for the first time last night sleeping on a cot with my Thermarest air pad under me, no tent, in my backyard during the current Arctic freeze sweeping much of the nation. Temps in my area dropped to 18 degrees F with a windchill of 5 degrees F. Sleeping in woolen base layer clothes of a lightweight long-sleeve woolen shirt, leggings and thick socks I was comfortably warm all night and slept just fine. I actually started off with a short sleeve shirt over the long sleeve shirt but got hot and had to peal it off almost immediately. I am 5’7”, so I have the regular model which was plenty long enough for me. I toss and turn sleeping so I like the extra shoulder room the Raven offers. The bag is soft and fluffy and very comfortable. The zipper works smoothly and the way FF designed the bag to overlap the zipper prevented any cold air from seeping in along the length of the zipper. I have had another FF bag for several years and the zipper has never snagged on it either.
