This bag is so comfortable! It fits about wall-to-wall in my Alps Lynx 1 tent and kept me warm on a 45 degree night. It is quite large for a 40 degree bag, much larger than some alternatives. But for a car camping sleeping bag, who cares about volume?
As far as the sizing goes, this lives up to the name of big and tall. As the title says, I am 6'5, 210lbs, and have very broad shoulders. This sleeping bag STILL felt roomy. This replaced a 15 year old Academy 40 degree bag that has aged to more of a 55 degree bag.
The clips that keep the middle and bottom ends held together when folded in half are a nice feature my old bag didn't have. It keeps the bag even when rolling it up. I have yet to be able to get the bag back into the stuff sack, but synthetic sleeping bags really aren't meant to be stored compressed anyway, so it isn't an issue.
My only complaint, not really much of one and not enough to remove a star, is that the clips that hold the rolled up sleeping bag looks pretty flimsy. I don't know if they will last more than a few years, but time will tell.
