HPG windcheater vs Red Kettle M20 wind shell

[Elmer J. Fudd]

I am wondering if anyone has used both. I’m looking for layer that will cut the wind but still be pretty breathable as I plan to use this piece while being very active. My family does a lot of deer drives and sometimes a guy goes from being a driver to having to post in the same drive. So you may have to stay stationary for an hour or so and you will not have any insulating layers with you. I just looking for something that would do a good job blocking the wind in this scenario that would also not cause me to sweat like I’m in a sauna. And maybe this piece doesn’t exist yet given that if you are keeping wind out it could be tough for heat to escape. That’s where I’m wondering if the pit zips of the windcheater offer an advantage for the m20
