Ok, let's get you sorted out here first. For outerwear, 686 makes hot stuff. When you buy your outerwear, just make sure you like the fit, and that the rating is 10 000/10 000+.
As for your bindings, is it safe to assume that you're going to be freestyling with this? Freeriding? A bit of both? No one can really truely recommend something that will fit YOUR style of riding until you tell us.
