Just curious if anyone wears one and how is the functionality when hunting. Look like they'd be great for long sits.

I've never tried one but think their mackinaw is the bees knees.  I wouldn't want all the extra material spreading out like wings when reaching around trees or twisting a bow through the brush.  I'm also not sure if it would work well while shooting if wind was coming from behind you blowing the flaps into the bow.

Maybe it's just me, but I like to keep my hunting clothes just loose enough to not be restrictive but fitted well enough to not have excess material flopping around.

I bought one last year and really like it.  It hunts very nice and is comfortable.  Plaids blend in very well.  I sat against a tree this past fall and had a doe with her fawns walk right by me at 5 yards and never looked my way.  I also have the possibles bag which os very nice.
