Quiet UL Alpine shelter?

Can’t beat a sil Trailstar for windworthyness.  Might be too heavy for you once floor etc taken into account.

Dunno about cuben version

I’ve got a Locus Gear Khafra in cuben and have enjoyed it but have not had it out in strong enough winds to be able to testify. I did get the extra tie outs option so that should mitagate at least some potential flapping. I have never used them, though.

It is a little tricky to get very taught sometimes, I will say. This is presumably due to the lack of stretch compensation opportunity that silnylon has. I suppose I’ve had it in gusts up to 15-20 mph without issue. I’d recommend it based upon my uses in the SE USA region but have not used it *extensively above treeline.

I have a triplex, altaplex, double rainbow and BA Flycreek HV2 (I have kids, wife and dogs so need all sorts of tents depending on who’s going).

I’m not sure if the issue with the duplex is the same as in my Triplex but the Triplex is so big when it’s just me and a dog or a kid and dog, that there really isn’t enough stuff holding down all corners of the tent to keep the wind from getting under it. If we don’t have 2 adults and a dog or two I am sure to put backpacks and other gear inside along the edges. This, in addition to my mass, hold everything down and is much quieter on windy nights.

The Altaplex is my favorite tent when solo no matter the conditions. It’s much quieter than the triplex in windy conditions and does much better than any of my others in snow. It’s basically a pyramid so it’s not surprising it does so well in adverse conditions. When in the alpine, I stack rocks to block the windward side and pitch it a bit lower so I don’t get too much breeze through the tent.

Mids of all sorts are quiet. And able to deal with the conditions that make other shelters noisy, or worse.

But going solo mids will probably always be heavier than true solo-dedicated setups.
