SM,
I wear the pants to the ghillie if I'm not sitting down in the brush. Most of the time I have my jeans covered by the brush while calling.
What looks like a white collar is the underside of my lycra camo face mask...I'm careful to even wear gloves while calling.
A white hand exposed is nearly as bad as exposing your face.
I do like calling exposed areas with camo pants though, or the ghillie pants.
Thanks,
Barry
