Could not imagine doing that same ride with mesh, would have killed me. Many miles in 80-100 with a cool vest is no issue. Good to 80º for me without a vest and vents open while moving. When wet underneath it's actually amazing how comfortable I am up to 100, feels about as good as when the Gerbings is cranked up when it's 30º, like cheating. I also pour water down the arms when it's real hot, that with a vest makes for comfy riding for a couple hours or more depending on your speed. You do need some airflow for the water to cool you though. Usually I keep the jacket zipped all the way up when it's hot using the vest, the vents have enough airflow and the less humidity the better the cooling. I've actually been quite cold when in the desert and going up in altitude the temp drops below 80 when wet in the Rukka.
I think people underestimate how efficient those small vents on the shoulders that act like air ducts and make air flow down your back and chest, but we are all different.
The other factors in my experience would be I wear an XD3 helmet with excellent airflow as opposed my street helmet most of the time, I also pour water in the helmet when refilling the rest and never wear cotton, only lightweight wicking high tech fabric underneath.
The Outlast liner for the Armas is also true to the marketing and better than any other liner I've have in BMW or Rev'it gear, flexible in various temps, good up to 75 (low humidity) and really helps keep you warm when in real cold temps. Great to use when in the mountains and the temps are fluctuating between 40º and 70º, no stopping needed.
To me, the Rukka Armas is a true four season jacket, I've ridden all four types of weather in a matter of days plenty of times. All day, all week below freezing or above 90, rain or snow I'm good to go.
sounds extremely uncomfortable 80-100f which is what I'll be riding at most of the summer. that's why I'll be using Motoport Mesh Kevlar most of the summer, then switch back to one piece Roadcrafter (single layer Goretex) when nasties hit. which Armas sounds like it does outstanding job with cold nasty conditions.
could do the same with one piece Roadcrafter, that you are doing with Armas... but why? it's gets way too hot with any Gortex 80f + unless a cooling vest is used. not with two piece Roadcrafter which is multi-layer and miserably hot over 75f. wonder if I used a cooling vest I could tolerate two piece roadcrafter to 100f ...
have you seen the comments from folks traveling with multi-layer Klim adventure suits ... gets too hot ...
only need to dump water on core at temps 100f+ .. just like riding bicycles....
why be hot riding 80-100f when Motoport Mesh Kevlar is comfortable without a cooling vest?
