First time I used my Nallo this tent it went down to -5 at night. I was comfortable all night long. However,it was clear to me that it would limited to cold weather use. Enter the mesh inner tent. Easy to substitute for heavier inner tent and makes this a great tent for spring and fall. I probably won't use it in the summer.
