I have also looked at them before and e-mailed the company a few times. Problem I have with them is that your legs are prone to sweat in them. If you take them off in the stand, then you are leaving your sweaty legs open. I can' t see waring them in a stand al day either. I used to buy everything I could to stop the deer from smelling and after years have stopped. Now what I concentrate on is entry routes to the stand, and keeping my human order to a minimum and avoiding sweating as much as possible. I mainly wear breathable material on my body and feet. I seem to be so much more comfortable and really have not noticed any change in deer smelling me out.
