I am planning a several week ski tour in northern Ontario and will potentially be facing minus 50 temps and high winds. I know this tent is designed for elevation, but I think conditions may be analogous. How does this tent do in extreme (and I ean extreme) cold
It's silnylon, which should be able to handle the cold better than PU coated nylon. The vent on top means that moisture won't coat the inside of your tent as much as a single wall tent that uses a membrane to be waterproof. With that said, the vent means you won't be able to warm up your tent at all, so make sure you'll have a bag to match the lowest temperatures. MEC Thor with a liner perhaps? I would also take a look at the Mountain Hardwear EV-2 or the Marmot Alpinist. This one isn't freestanding, so that might be a problem for setup in high winds. If you don't like those designs, you'll never go wrong with a Black Diamond Bibler tent.
