anybody know what kind of harness this Catman dude is using? he's been using it a lot on his most recent videos

Message him on Facebook.......he'll likely respond within an hour or 2 (if he's not in the woods)

It’s a lightweight saddle like this:

Saddle

I want to give this saddle hunting a try. Just can’t make myself spend that much on one.

I bought an aero hunter kestrel this year and while it has taken some time to get used to it and find out what positions work best for me I can tell you I won’t be going back to either of my summits. The versatility is awsome and like I said once you dial your system in it’s super comfortable. Plus the ability to shoot all the way around the tree is huge benefit, it’s a killer tool.
