- Familiarity: I've used it several times
I've used my Neutrino 600 for around 10-12 nights so far. Temperatures have ranged from the 40s down to the mid 20s and it's been great. I mainly backpack along Lake Michigan and Lake Superior and it's kept me warm and toasty while the gales of November were screaming outside my tent. The fit is perfect for me (6'1", ~175lbs). I move around a lot at night and find the roomy shoulder area to be just what I was looking for. I pair it with a Thermarest Pro-Lite Plus and sleep like a baby. I had previously tried a Kelty Light Year (20) down bag, a Sierra Designs Ridge Runner, a Marmot Sawtooth, a Marmot Pinnacle, and 1-2 other bags. This is by far my favorite of the bunch as far as fit and overall feel/ quality. The others were all really nice, but the Rab is exactly what I was looking for and I look forward to using it for many years to come!
How can the shoulder/hip/foot circumference...
How can the shoulder/hip/foot circumference be 27.5/20.5/16 in. when most bags are twice these listed numbers (and a 31 in. waist size is small for any adult)?
The down is the most expensive component of a bag and the down fill weight should be listed on all down bags.
Nope, that's not right. Maybe not circumference, but diameter? Rab makes good gear, but their site has no info on actual fill weight or dimensions that I can find either. Oh well, there's always Western Mountaineering, where everything you need to know is out there and proven by a more accurate rating system . Haha, and they look cool too, which is about as far as some people get in figuring out what bag to buy.
The amount of down is a part of the name: 600g. Turns out it was listed right in front of your face.

Everything about this bag is incredible. The outer fabric is really soft and beads water right off. This bag seems loftier than any 10 degree i've ever seen. I've been out in this bag in some pretty cold winter weather where it was below 0 outside the tent. One touch and you'll be hooked.
