The Kelvin aerolite jacket would work pretty good for that. I love mine lightweight but very warm. Material is kinda loud for bow hunting on its own. But underneath a stratus it would be prettt quiet. If you don’t want to spend that much the outdoor research shadow jacket is very good as well...
I have no clue if/when it would be released. But they aren’t going to purposefully hurt the sales by mentioning something that could be a year or 2 out.
Inside source. But I seen the pattern. It looks good. Not sure of the technology behind it. But I would be careful dropping a bunch of money on EV2 right now if you like the most current stuff
