User Review: REI Sub Kilo +20
Price Paid: $170
Great bag. Light, tiny, warm. First use was a moist 35F in the Beartooths, chillier feet than expected, small hot water Nalgene sent me to dreamland in no time.
I've only counted 5 down fluffies in the past 5 months that I've owned it, literally, lots of use and still like-new. I do use a silk liner, just personal preference.
