yes mine is the thermal house. I won't have any house from now on unless it is thermal. that is how much I believe in the thermal houses now. as for the thermal Nanooks being black inside, the last two or three years they have had the black fabric inside prior to that it was a light gray fabric inside but was still thermal. the change was made because people were wanting to be able to do more sight fishing out of the Nanook but the gray fabric let to much light in. what I am hoping for next year is that Clam will expand their stealth line of houses and make a Nanook Stealth. I may have to suggest that to the higher up at Clam when I talk to them again. over all I am looking forward to running this house this season. Next year I have my eye on one of the Kenai Pro thermal Stealth's and the Voyager Thermal Stealth. that would be unless they took my suggestion about making a Nanook Stealth then I might look at that if they made it.
