up for sale is a Mountain Hardwear Trango 2, 4 season tent. Look at any major Expedition (K2, Everest, etc) and you will see the same model of tent in the background. This is the older version than the current (the changed the door and clips for the worse)
This tent has not sat at base camp in high altitude for months though, so it’s still in excellent condition.
It comes with stakes, tent, fly, and footprint.
My photo, winter at J-tree 11deg and dry.
Not my photo, showing the fly
Not my photo but there it is!
