I've been using this bag with the BA sleep system for two wintyers now and it has yet to let me down. I've used it in temps down to -10 and, while I did need to put on a few extra layers, this bag kept me toasty and comfy. The extra room is a big plus too. On the down side, it is a bit bulky and heavy, so if you're an UL camper, this may not be the bag for you. Also, I'd really like to see BA use a liner material other than cotton, for all the obvious reasons (dries slow, is cold when wet)
"Great, roomy bag for a restless sleeper- will get you to 0 degrees no problem."

Great bag! Used it with an Exped Synmat down to -2 degrees w/o getting chilled. My son had my -20 Elk Park bag (sneaky little scuzzbucket), so I got to test the extremes of this bag. These bags are well worth the expense/space/weight of the needed pad. My wife hates the fact that I sleep with "Big Agnes" when I'm camping without her! She wants the company to change their name!!!
