I agree that the Akto is a very strong and high quality 4-season solo tent. But I must add an anecdote to illustrate the what I feel is the tent's main weakness. In early October of '06 we were expecting Boulder's first snow of the season. With a predicted low of maybe 28 degrees, this promised to be one of our classic wet shoulder season dumps, and they thought we'd get maybe 3-4" of snow after a few hours of light rain. It would be a good night to test my Akto in moderate heavy snow conditions.
I pitched the tent in the back yard, and I crawled into my bag around 10 PM while a light cold drizzle was going on. At midnight, I woke up with cold nylon in my face. The 3" of wet cement snow was too heavy for the tent, and it sagged terribly, mainly at the head and foot. I got up and went out to clear the snow off everything, and I re-tensioned all the guy lines to get my tight pitch back. After another 2 hours, more snow (3") had accumulated and I was kissing nylon again. Again, I got up and cleared the snow. No need to re-tighten the guy lines the second time, as the tent was quite taut. Back to my bag for a few winks. This time I slept through for 4 hours, but when I woke up it was a near disaster. Another 6" of wet, heavy snow had all but collapsed the tent. The single pole remained intact, and all the guy lines were secure, but the head and foot ends of the Akto were nearly squashed down to ground level. I had a hell of a time finding the zipper to get out of the tent. So--the Akto doesn't work at all in that unique "a foot of wet, heavy snow" situation.
But one doesn't encounter those conditions very often. In my mind, the Akto performs superbly in all other types of weather. It withstands wind well, and large amounts of rain too. It is a warm tent that is a joy to use in 10-15 F. I expect that it would shed blowing cold, dry snow with ease (but beware the heavy, wet stuff!)
