Since we are experiencing the Arctic Vortex here in Pittsburgh I thought I give my cold weather gear a test. I have 3 Sleeping bags (15, 30, and 40 degree)and wanted to see how the Marmot Plasma 30 bag holds up in extreme cold weather. So outside I went to setup my sleeping gear.
Here is what I used and wore:
Ground Cloth was Tyvek
1/8 inch Gossamer Gear pad went under the mattress
Mattress was XTherm large
Sleeping Bag was Marmot 30 Plasma
Ti-Goat Raven Omni Bivy
Clothing:
Icebreaker Thick socks
REI Silk bottoms
tshirt
Ibex Hooded Indie
Lightweight Outdoor Research Gloves
Mont-bell ex light jacket
Black Diamond balaclava
To my surprise after 20 minutes I was quite warm and would have no problem using this same setup on an actual trip in temps well below 30 degrees. I used a digital thermometer and the readings varied from 3 to -14 degrees.
