Hey guys, here's how I'm setting up my rig for a " cracking cold" night below zero. The only thing I didn't set up was my Old Man Winter since even though it was windy , it was crystal clear and I wanted to still take in the amazing view through the vent in my XLC bugnet/winter cover mod. I did have an issue with my Burrow " bridging " but adding in my DIY Gore-tex heavyweight fleece TQ liner helped to minimize the effects. The digital thermometer in my pocket read 77° as an inside temp so I'd say I stayed plenty warm even though the " real feel" temp was well below the -10° rating of my quilts. I'll also post the companion vid to this one " My winter clothing options "
