This is probably the best quality affordable 4 season backpacking tent out there. And what I mean by that is you can live in this tent for about 4 seasons before it wears out. I would know because I've done it twice now.I originally purchased this tent two years ago because I had been camping in Utah for several months and it was getting colder and I wasn't confident my other tent would hold up in the winter. I looked at a lot of tents online and the thing that caught my eye about this one was the skirt around the foot of the tent. I had previously camped in Idaho winter weather in a similar tent that I think cost around $300, and it was a great tent except that the wind would occasionally blow snow up underneath the rain fly. When I saw the skirt on this tent I figured who ever designed it probably actually knew a thing or two about camping in the winter (and the price was unbeatable) so I went ahead and purchased it. And then I slept in it for the whole winter. And then spring, and then summer, and then fall. By that point the zippers had started to wear out and the rain fly had been weakened by UV light from being outside all summer and fall. And so I purchased two more of them. I gave one away and a little over a year later, I'm sitting in the second one in November in Idaho writing up this review.Who ever designed this tent knew what they were doing. Simple, elegant, durable, versatile, and light weight are all words that describe it. The inner tent has a waterproofed nylon floor to keep out moisture from the ground and the right amount of mesh on top to provide ventilation to minimize condensation and keep mosquitoes and insects out. The outer layer is also made from thoughly waterproofed nylon such that no water can get in from the outside. The seams are properly seam taped. The skirt prevents wind from blowing snow or rain in. And even the vents can be closed if you're in an extreme blizzard. The only moisture that you deal with in this tent when it is set up properly is condensation. There is really no way I know of to avoid having some level of condensation in a small tent in the winter (except possibly holding your breath all night) but the elegance of this design is that almost all the condensation condenses on the outer layer of the tent and runs down into the dirt. That way everything in the inner tent stays dry. On really really cold nights I have noticed a little bit of frost in the inner tent, and sometimes in the mornings when the sun is melting the frost at the peak of the rain fly a little bit will drip down through the mesh rather than run down the side into the dirt. But overall, it really does stay almost bone dry all through the winter.I've slept in this tent during strong wind, torrential rain, 3 to 5 inches of snow, and single digit temperatures. It handles it all just fine. I think it could handle significantly heavier snow but 3 to 5 inches is the most I've had in one night before (I checked it with a tape measure). If you are expecting realy heavy snow, I recommend using the ties on the inside of the rain fly that tie around the poles because this will stabilize the poles to be able to hold significantly more weight without buckling. One review said they got 2 feet of snow in one night. I'm guessing that was a bit of an exaggeration, but I would say that this tent is easily strong enough to hold 10 to 12 inches of snow without collapsing.*Update, It's January now and I've moved to northern Idaho about 8 miles from the Canadian border. It hit -18 degrees Farenheit the other night and I'm still sleeping in the tent every night.
