I bought a Sub-Zero 4 man at Cdn Tire this year - the instructions are on a piece of material sewn into the carry bag. At the bottom it says Eastman and gives the Eastman address... (?). Same factory in China maybe? Sub-zero simply the Canadian importer?

So far I think it's just fine - easy to set-up and take down although the stress on the needle holes from the stitching make me wonder how long it will last (I'll find out ha ha).

No problems in moderate winds with set-up or take down.

Holds the heat well (it's a tent though) and you sure can tell when the sun is out - the black picks up the solar power just fine!

Lightweight and easy to pack and transport ++++
