User Review: Marmot Aspen 15 Explorer
Temperature Rating: 15 F
Price Paid: $59 (floor model)
I bought this at Dicks and used it Jan 2010 on the AT in New York. It was 20F and snowing.
The Marmot Aspen Explorer 15F kept me warm at night. The temps dipped to about 10F early morning. I did sleep in base layer and fleece, with body warmers in my socks, and we were in an AT shelter. But that bag should keep you warm down to 20F.
It packs up small and light. and can't wait to use it again.
