Scarp 2

I love my Scarp 2!

TarpTent scarp or stratosphere both come with a solid inner option. I have a Scarp and love the solid inner for snow camping. That’s really the only time it gets used though as it’s kinda heavy, for the other 3 seasons where I use a mid. https://www.tarptent.com/product/scarp-2/

Can vouch for this, I’ve got one and it’s my dedicated winter tent. I’ve had it out in some very harsh winds and it’s an absolute rock. I ALWAYS use it with the crossing poles though.

I used the Tarptent Scarpa II in Iceland during some pretty windy weather, and it held up beautifully. I was using the additional tent poles, though, so that did add to the weight.

Is it for one person or two? How are you defining 4 season? Are you expecting snow loading, or just stormy/cold conditions? The Hilleberg Nallo 2 is certainly a good tent. Have you also looked at the Soulo and Unna? The TarpTent Scarp 1 (with crossing poles) is more than big enough for one person with gear. The Scarp 2 feels less sturdy in strong winds. I have both. Have you looked at the Nortent Vern 1 (or 2)? I'm planning to buy one soon for winter camping.

not sure why 30° enters the equation since tents are not what keeps you warm. They keep the wind off you and they keep you dry in the rain. If you get a hot tent designed to be used with a wood stove, that’s not really great for backpacking unless it’s winter and there’s snow everywhere so you can put it on your pulk. And it only stays warm while the stove is operating. If year around doesn’t include lots of wind and snow, any tent designed for three season use will do. If you intend to use a tent in winter blizzards, you need two tents, one that works well in high winds and takes a load, and a three season tent. True four season tents are designed with extra guylines inside and out, and durable materials to withstand snow loading and 50+ mph winds, often floorless so one can increase space by digging down into snow. You’ll want snow stakes instead of regular nail stakes. Tents with steep sides to shed snow or long dome type with a large vestibule work well. Hilleburg and MSR have models that are designed for 4 seasons- heavy and weather worthy. I have a GoLite Shangri La - floorless, vented at the top, three person version, weighs 2.5 lbs with a single pole. I didn’t bother with the mesh inner because I never intended to use it unless there is snow. It is not freestanding and doesn’t have to be. it’s no longer in production, but there is a similar version that I believe is made by the company that bought Go Light. The other tent will have an inner bugnetted layer to keep mosquitoes off, regular stakes, lighter waterproof fly and be whatever shape you want. I have a variety of these that I have purchased over the years. My favorites were the Lightheart gear - I wore out the first one, replaced it with the same model, and then it was stolen from the garage when a roommate left the door open. I replaced it with a Durston Xmid. In the past, I have used several models of Tarptent. They also have a four season model called the Scarp. You might have a look at their various models. They do a balance of weight and durability. They are far too light for true severe winter conditions but would be okay generally for use in snow with appropriate stakes.
