Hilleberg - Akto

I have a Tarptent Cloudburst 3 with the 3rd pole, it's held up in winter conditions in Mt. Hood NF, it's not UL at 60oz but it's also a 3p tent, although it's a hoop-tunnel tent and not a dome tent. I have a 1p Hilleberg Akto that has done great in the 4th season as well, but it's the same weight as the Cloudburst 3p, and again, not a dome tent. I recently scored a Big Sky Revolution 1.5 that feels very stormworthy but I haven't had it out in weather yet, I have the mesh inner but I'm considering getting the solid inner for it to turn it into a possible 4S tent. There are some other Big Sky tents that look tough yet still light, like the Chinook, MSR Access line of tents are pretty robust but IMO too expensive, and as someone else already said, the Slingfin Portal.

My Hilerberg Akto has withstood storms as bad as any I would want to be out in. Not designed for deep heavy snow but unless your planning on taking up ski touring or snowshoeing somewhere that shouldn't be a consideration because if it snows too heavy for an Akto you won't be walking out in just boots, it has a solid inner which helps to retain body heat which is pretty much the only source of heat you'll have most of the time. At approx 1.5kg weight it's suitable for backpacking . Though not designed for it a modified Akto was used succesfully on a solo expedition to the North Pole, not bad for a backpacking tent. If you really want the option of camping during heavy snowfall then the Scarp 1 with the crossing poles seems on paper to be the most versatile option as you can use it in summer without the extra poles though I have never used one. I've used a Hilleberg Soulo extensively in heavy snow and it performs just great but then If I just had walking boots in that kind of snow getting out would have been a survival situation so I do think it's more of a specialist tent.

For alpine, windy or snowy conditions, nothing beats a Hilleberg. Pricey though. Akto is my favorite one man shelter of all time (tunnel style). Soulo for a freestanding one man, but with a significant weight penalty. The Rogen is a sweet freestanding two man design. Has more airflow than some of their other models, but will handle wind like a champ. Excellent weight/space/weather compromise.

I have a Hilleberg Akto and can sit up cross legged in the middle, I'm 5'11". But I only really sit up if I'm cooking. If I'm not cooking, I'm probably reading laying on my back. And I can and do cook laying on my side, sometimes. I would give it a chance. You can go bigger, but weight will also increase.

That’s why I have a Hilleberg Akto. 15 years old and still going strong. Not a single tear or bad zip. 500g weight penalty

Hubba tent has a single top tube, this design is made to be lightweight but it cannot withstand wind. You have to choose tents with another type of construction: half barrel designs (papa hubba type but smaller ones), two arches crossed two times designs (elexir type) or several arches forming a dome designs (3f ul Taiji and it's Hilleberg original).

I've used both. I find Hilleberg 1-person tents to be pretty nice size-wise, but there's no denying a 2-person tent feels luxurious. Right now my only tent is a 1-person tent.
