A rock solid beast, but because of that it's heavier. It's 3-4 season convertible with zip out panels. And three support poles instead of the two you normally find on a tent of this shape. The poles feed through in sleeves, not loops or clips. This is a lot more stable and solid, at the expense of air movement. This lack of air movement between tent and fly is great when it's cold out but can make the tent too warm during hot weather, even with the 4-season panels open.

This tent is no longer made. I picked it up for next to nothing from REI on closeout. $149!!! Previously selling at right near $400, and that was ten years ago.
