I know a lot of guys who like them for moose hunting, stalking and calling. Yes they do have a little more noise than pure stil-hunting pants, but to me they are a little more versatile. I stalked up to and shot a feeding doe in the open last year wearing them, but that is only one example.
I have suggested to Sitka to look into a plaid pattern for the Stratus line to gain even more attention for the traditional hunter. We will see. But to me these are a very usuful pant for multiple hunting situations than just sitting in a tree. Ha!
