I am absolutely not bagging on the BA tents, because I am totally satisfied BA owner. I just think this thread has gotten a little off course from what the OP was looking for, and I don't want to see somebody getting in a bad situation. A pic is worth a thousand words. This is what i came back to after a long day of hunting in the wet snow and moderate winds. 7800 EL. first week of November, My sleeping bag was floating inside on about 3" of water. Most sleeping bags would have been soaked and sunk and I would have been in an even worse situation.
To be fair, most three season one man tents would have been squashed by wet snow like that I suspect. There just isn't a lot of one man tents out there that meet BRWNBR's "bombproof" specification. I'm another Hilleberg fan, and have weathered a number of snow events above treeline in a Nallo, but you have to babysit them in wet snow just like any other. I haven't done snow in an Akto yet (although I own one now), but I'm sure the flat ends would catch snow and sag without someone to kick it off once in a while.
For closer to "bombproof", something that looks tougher (and roomier) than the Akto at about the same weight might be the new Hilleberg Niak 1.5. It's not out yet, but is supposed to be soon. I'm going to assume it's expensive, but BRWNBR is a guide, and might be able to get a pro discount?
