The most wind-worthy solo tent I own is the Hilleberg Soulo (#1). I simply never, ever worry about it. I’ve used it in gales up to sustained 70 mph winds and with earplugs, have slept ok!
I’m also *lucky* enough to have a 3-pole Caffin tent – that’s a close second (#2). I’d be OK with either of these tents in just about any condition. I have legit fears about the carbon poles in the Caffin tent, because I’ve broken them during setup (my fault). They’ve never broken in a storm – just max out the guyline options and be careful. It’s worth it! @rcaffin, c’mon, mass-produce these things!
The Hilleberg Akto and Hilleberg Enan really need a double arch pole to be considered “storm-worthy” in serious conditions. They’re a bit wobbly otherwise, but strong enough not to fail for the most part. I’ll rate them later.
The Trailstar is as good as it gets for a 1- or 2-trekking pole tent, but it has to be pitched pretty low to get that benefit (the geometry allows for this) AND it has to be the silnylon version. DCF doesn’t fare well when large panels are involved. If it’s pitched high enough to be “comfortable” the wind actually caves in those big walls quite a bit. I’m not as enamored with the sil Trailstar in extreme winds as others.
The most wind-worthy DCF tent I own is the Locus Gear Khufu DCF-B. It’s quite a lot more stable than the Akto/Enan. Low stretch, great manufacturing precision, lots of tie-outs, low profile. It’s my #3 preference for extreme winds.
#4 is the Trailstar or Akto/Enan with 2-arch poles.
#5 is a tie between the Tarptent Notch Li and Locus Gear Djedi.
Hillberg Akto or Enan with 1 arch pole is #6. Akto is a little better for winter/snow. Enan is better ventilated for summer, and lighter.
Most of everything else I own (1- or 2-pole trekking pole tents) I wouldn’t trust *much* in a real storm (with sustained wind speeds > 50 mph winds) above the treeline.
I no longer own geodesic domes (except the Hillberg Soulo), except the Nemo Dagger 3 (my wife and I use this now for it’s livability:weight ratio), so there’s a caveat here…(real geodesic domes like the NF VE-25 are very good) – I just don’t spend a lot of time in environments where wind destroys tents.
Most “ultralight” tents do fine with occasional 40 mph “gusts” (not sustained), which is what we mostly experience during the “extremes” of summer above treeline here in the mountain west.
A bivy sack pitched in a strategic location is actually pretty awesome in extreme winds…
