i BOUGHT THIS ONE, and i took it to 20000 ft.
PERFECT!!! no more to says, perfect!!!
The weight is a miracle, really light tent, perfect for an expedition.
I took it to the caribbean see, 3 days raining like crazy!!!
and worked perfect for me(i was alone, is a 2 person tent, but i was alone), no rain inside the tent, worked pretty much for me.
I tested it on 2 different weathers... for other people didnt work proppelry, for me fine! if you need more information just ask me!!!
