it caught my attention and I have been thinking about a new shelter, now I am thinking about insulating what I have and buying some new rods instead
It may actually work, and it's set up so the mylar overlaps the next piece of insulation unlike reflectix. Air leaks through the fabric are one major weakness of my 1660.
BTW, check out your local Goodwill. Someone got rid of a perfectly good St. Croix rod, a backpack seat, and an arctic tip up at the Wayzata store, and I walked out of there with all 3 for $14.
