Tested out my just completed 2/3 sewn PLUQ last night. Had on a T shirt and a medium weight jogging suit. It was 62* when I turned in for the night and all was good. Woke up at 11pm with a cold back side, at 49*. Wasn’t trying to make it thru the night, just wanted to know what the limits of this UQ would be for me. So I got up, went inside and made few notes about the results. As everyone knows or should know, test new gear close to home, or have a bail out plan.
