Just received a new Scent Lok Head Hunter jacket and pant set as a gift, along with the mid weight Scent Lok base layers. It seems very comfortable, however I do not have any experience with them outdoors. Knowing it's going get pretty cold this weekend, I'm curious if you guys think I need to add another layer or if that will be enough. I get cold really easily, and there's nothing worse than trying out new gear and freezing your butt off.
