Kunai 2P

For use in the snow and high winds the kunai is much better. I've used the dagger in the snow when there is no wind, but it would both be too cold, and might be destroyed in an extreme snow storm Kunai is much better suited for winter / alpine conditions

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

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.

I am 6’4 you need a 2P I like my Nemo. You also need a tall sleeping pad or your feet will be hanging off and you need a tall sleeping bag. Yes, it is extra weight but it’s the price we pay for the fun of it!

We have 4, was 5 but I turned one in to a gear reseller and got $40. It was a 30 year old 2p thru-hiker mountain hardware that would not die. We also had a North Face 3p that was awesome, it was barely holding together with patches and 10 layers of seam seal, finally destroyed in a hailstorm in Golden Gate state park. Oldest to newest: 1. huge Coleman for car camping. 2. 3p mountain hardware 3. 2p (roomy) Nemo 4. 2p Sea2Summit (small) ultralight. Depends on what we are doing, we have everything for 3-1/2 seasons.

Nemo tents pack pretty small and are light. The new dragonfly seems like a good option. If it’s just you and another person a 2 person might be more than enough space.
