Hung my HH Expedition Zip in the back yard last night. The temps got to the lowest I've hung in. 25° was the low. I had my AHE Lost River in digital camo under me and a Wally world mummy bag as a top quilt. I slept like a coma patient until 4am when I realized my UQ shifted from underneath me on one side despite my new UQ triangle thingies in place. I didn't use the HH tie outs in hopes of helping to keep the UQ in place. Any suggestions or experience welcome. But all in all I had a good night. I woke up refreshed and hit the local mountain bike trails for a good ride !
