One Double Rainbow one BA Seedhouse. We both just use an extra groundsheet against the snow and I line the inside floor of mine with a cut to fit piece of discarded Wildland Fire Shelter under my pad. My buddy puts all his extra gear (gaiters, jacket, rainpants, etc under his. If it's handy, and we have some daylight, we will sometimes throw down a good layer of fir boughs too. The first pic, in the deeper snow, we woke up to 3 degrees F. I never got cold in the tent but my boots were a bit stiff
Got back from a month of guiding just in time to help a good friend kill and elk and pack it out. And kill a mule deer for myself in a place that isnt know for trophies but is one of my favorite drainages. With a day to spare before the season ended. Its been one hell of a ride!
