Kunai 2P

Backpacking AND mountaineering? Mountaineering tents are built to be erected above treeline or on snowfields or glaciers, and designed to withstand high winds and potentially heavy snow loads. They usually have solid inners and more robust fabric and/or pole systems. A light mountaineering tent will be heavy for a backpacking tent. You can look at tents that straddle the two categories like the Nemo Kunai 2P, TarpTent ArcDome Ultra 2, Samaya Alpinist 2 Ultra. I wouldn't consider the Nemo Dagger a mountaineering tent. It's a 3 season backpacking tent.

Nemo Kunai is a great option for year round use.

Nemo Kunai 2p / 3p I've used it for about 60 days over the past 12 months, up to about 5100m. It's held up great in storms, and weighs about what you're looking for. Great in winter and summer, low lands and high peaks. You could also consider Hilleberg tents for high durability and quality, though at a very high price point. Samaya I would only buy if I was doing a cutting edge expedition, with the knowledge that you might only get a few trips out of it, but oh boy is it a lightweight tent

I got a deal on a Nemo Kunai and have been happy with it. Ive used it extensively in the Adirondacks & Whites in the winter, and some mountaineering trips out west. Just under 4lbs

I am using multiple naturehike tents and putting them through hell without a single issue to see if they will hold up to my multi week expeditions. Have a nemo kunai, which is good but no better than my naturehike tents. EXCEPT the naturehike are $160 cad. Highly recommend checking them out and see if one model fits the bill and ignore these people recommending $1200+ tents that will do the exact same thing but less waterproof and most likely sag when wet... have a few reviews if interested, but everyone looks for something different in a tent. Tents are not buy once cry once. You are paying for a name after a certain point unless you're summiting mountains with specific expedition gear or something similar.

If you're planning on Denali, Logan or the Himalaya then go with a full four season tent. Snow load and the high winds will crush a lesser tent in those condition. If you're just doing winter camping where the weather is predictable then get a three season or 3+ tent. The Nemo Kunai is a good option and about 4 lbs or the REI Arete ASL is a roomier choice and solid at around six lbs. I'd wait for the upcoming sales next month to possibly save quite a bit of money.

Love my Nemo Kunai. Packs small and durable on ice and snow and adds to warmth by blocking cold winds. Well as one would expect. It'll be with me on Mt Baker in June.
