That was a great video! In my youth about 40 years ago on a winter camping trip to the Pemigawasset Wilderness in NH it got down to minus 33. I can't begin to tell you how primitive our gear was! We slept in a 3 season tent on a half length Thermorest pad in a double sleeping bag. I didn't even own a pair of snowshoes. Just trudged about 3 miles into the campsite with about a 60 pound pack. I woke up the first morning with about 3 inches of frozen breath on my chest. We spent the day building furniture out of logs and keeping a fire going. We ate and drank water non stop and played "Indian Hockey" in a clearing we made on a frozen beaver pond. The trick was to not stop moving! I'd do it again if I could find anyone crazy enough to go!
I'm going to be out this week - I'm sure i'll get single digits in NC.
Tipi Walter is out right now - I'm pretty sure - - he has like a negative 30 bag
in his Hilleberg Tent - it's literally bombproof
Packed up and hitting the trail here in an hour or so. This is really a unique opportunity for those of us in the Southeast.
ok, had to drive the daughter home so I did not get the chance to do this until last night
the low ended up -10 with light winds
used a full and a short thermarest
bivy
-20 sierra design 800 fill bag
base layer, fleece layer, insulated pants, down jacket with the zip off sleeves over the feet, base layer gloves and down mitts, face shield over the nose
kicked out a trench in about 7 inches of snow
was out for about 7 hours, was fully warm and estimate this would be true for another 5 degrees and some more wind
certainly this system would be reasonably comfortable to - 25 and keep one alive overnight to - 35
no big issues with condensation / frost as I try to expel my breath outside the bivy
some cold spots on the feet when they were pushing outward/ compressing the insulation - felt no cold spots from the ground
Glad you made it, George. Not my cup of tea, for sure.
will look at the forecast for mid Feb, unlikely to carry a -20 bag, would likely stay with the -5 I usually use in the winter
