Never used EVent. The point I got from that link is the Rab doesn’t make jackets with Neoshell anymore and they were mentioned the most here.
Got the point, but they seem to have replaced neo by Event and that doesn’t convince me based on my past experience.
Reading a lot around, I have the feeling that Marmot and Westcomb may be selling the largest amounts of Neoshell jackets.
Since they are not that well represented in Japan, I am currently likely to invest in either Millet or Mountain Hardwear that both have dedicated brand stores within 100 meters of each others 10mins train away from my house in Tokyo. The Millet White Neo jacket has better technical appeal for ski touring with a powder skirt,... (and is definitely featurewise one of the best options in the world regardless of the material it uses) while the MHW is a more streamlined design with one version looking like a standing Belgian flag 🇧🇪 which I find hilarious in its own right.
If they work well this winter I may try another neoshell as my lightweight summer rain jacket too and here I am not sure yet about the best option.
Cheers,
Bernard
