Yep, very truly yours Stephenson Warmlite. Its a newer, shorter version 2C, double wall (2R) with the internal wind stabilisers (funny "flaps"), reflective liner, no windows, standard door and standard triple vents.
So, I've just weighted it (tent and poles, no stakes) and it came down to 1048 gram (~ 2.3 lbs).
The tent survived the epic much better than us. First, got hammered by the ice avy off the headwall, then by spindrifts on the Coe gl drop offs, no probs. I was actually swept by wind gusts, fell, tumbled and broke one of the pole in my hand while we were taking the tent down. Still, the second day we pitched it again with the broken pole and hunkered down for another 16 hr - I was really dreading the idea of spending that time in a snow cave
The higher winds the less condensation or ice build-up in the tent. None was on this trip and its after cooking and melting snow for 1 gal H20 inside the tent.
