Hilleberg - Red Label Series (3P models)

This absolutely. A red or black label hilli is the answer if price is no object. I have an allak 3 and the build on it is so far beyond any other tent I own.  Those zippers are just a joy to use. 

“Price is no concern” then go here but you’ll be tripling the price of what you posted. https://hilleberg.com/eng/products/tents/red-label

~~Winter camping can mean many things. The Nallo isn't a 4 season tent. Specifically, it isn't adapted to snow. Those cat curves on the lower perimeter of the fly are practically impossible to bury and the spindrift will flood the interior. You will regret using the Nallo in full on winter conditions (blown snow).~~ If you have a very limited budget and need one shelter to do it all, your best bet would be a mid with as many sides as you can get/are willing to carry (i.e., a rectangular pyramid -> a hexagonal mid -> an octagonal mid). Edit: My comments about the cat cut on the fly is due to confusion with the Anjan! My apologies for the confusion! FWIW, I've personally used and owned at different points 3 of what are now called the Black Label tents and 6 of the Red Label tents.

The Nallo red label is absolutely considered a 4 season tent and I would not hesitate to use it in the winter under most conditions. Only the black label version would be better for extreme arctic conditions.

Hilleberg is solid but damn those prices hurt. If you're not doing serious mountaineering the MSR Hubba series is way more reasonable and still built like a tank

People shit on hilleberg prices till they use a hilleberg in less than ideal weather. I’ll tolerate the price for the long life and ability to handle some nasty weather. Most places in the states below tree line don’t need one though.

Hilleberg, TarpTent, SlingFin, Samaya. Real expeditions are more likely to choose Hilleberg. Their strongest tents are not super light, but they are made to withstand serious weather.

if money isnt a thing then hilleberg, black label series, a staika model kept me and my guide protected and safe when it snowed 14 inches on a high country elk hunt, they are awesome, im from Tennessee we dont need best quality expedition tents generally even in the eastern mountains. but having used that one for a week i can say that one was great.

I swear by my Hilleberg, but that's a terrible deal, even on a great tent.

Get a Hilleberg! 😂buy once cry once.

Hilleberg is the tent for severe weather. They have different lines depending on how you want to trade weight versus sturdiness. None are "ultralight", but that is not what you are looking for in extreme cold/winds/snow.
