TJM and myself enjoyed an evening out near Black Pond, off the Linclon Woods Trail in New Hampshire the evening of 1-22-2011.
We were a little disappointed at the temperature of about 7 degrees, we were hoping for at least bit below zero. Our equipment was perfectly up to the task however, thanks to Hammock Forums. The pictures will tell the story. My HH set up was covered by a Hennessy poly hex, with added DIY closed ends, not shown in pictures. My DIY 5" down UQ worked great. A blue wally pad, w/ 1/4" poly batting/dbl. IX/SB insert, IN the sleeping bag was toasty. Only Carhart poly long johns and wool socks were needed. (with a hot water bottle)
Some of the pictures may have a wrong default date, because I took the batteries out of the camera to keep them warm.
My DIY insulated overcover, which is velcro's to my HH SS undercover was sealed TOO well. Although it held steady at 44 degrees inside all night, it also resulted in a GREAT deal of condensation, and my down bag was soggy in a couple of places. The digital humidity device showed 85% inside the hammock enclosure. Humidity outside the hammock showed 20%. Had we been out for more than that night, it would have been a BIG problem. Lesson here is adequate venting is essential !!! But we were were both warm none the less.
