What temps are you planning on using the Stratus for? I have both the Fanatic set, and the Stratus set. If I was planning on 40 and under I would get the Fanatic. 40 and over the Stratus. I wore my Status set last week when it was 36 and 10 mph winds in the face. I had a 200gr set of merino base layers. stratus vest, jacket and pants. I was also wearing my fanatic hoody (pretty much hooded base layer) I was pretty cool when the sun went down. That said it would have been worse if I didn’t have my fanatic hat and neck gaiter in my pack when the sun went down. I do believe if I’d had my Sitka heavy base layer pants on I would have been fine. If you want cold weather gear and can swing it you can’t beat the Fanatic system. I always wear my stratus vest under it in case the jacket gets to be to much when the sun comes out. The zippers on the legs of the bib help tremendously also.
That said, I don’t know a thing about the Asio, but I do obviously wear a lot of Sitka. I’ve probably been given 3k worth over the last few yrs, and it’s good stuff. If I were buying a mild weather set, and a cold weather set. It would be the following:
Mild weather:
75-40
Heavy Base layers for the colder side
Fanatic Hoody
Stratus Vest
Traverse pants
Stratus Jacket.
Stratus pants
40 and below:
I would add:
Fanatic bibs
Fanatic Jacket (zipper and pockets are wired but they are designed for hand warmers to stay warm by air circulating)
Fanatic Hat
Fanatic gaiter.
I also have a Celsius jacket I rarely use, but when it’s 0 to neg temps I wear it under the fanatic.
I also have a fanatic vest I will throw on over the Stratus if a cold front is coming in, and temps are going to be dropping and wind is picking up.
