Just wanted to leave a quick review on my 20° Incubator (+1oz) and how well it did down to 7°.

I recently went out for the Huron Hang in northern MI. Temp was 7° when setting up and probably rose to 10° for the majority of my sleeping.

I was worried about taking it into single digits, but with temps in the mid-20s and 30s the next two nights, I didn't want to pack extra insulation for just one night.

I slept solid for 8 hours! No cool spots or drafts to speak of. I was wearing a Capilene 3 zip top and bottoms. Had my 100wt fleece and down jacket on standby but stayed in my pack the whole time.

Great peace of mind for any future winter trips!
