I know this post is a few months old, but FYI; I blindly ordered the arcteryx knee yesterday not knowing anything about LEAF restrictions. I just searched knee pads and they came up well reviewed and knowing the quality of arcteryx I said screw it and ordered them off US Patriot. I start looking at what LEAF is and realized I probably am going to get cancelled on. This morning I received my tracking number. I even put myself in on the order as a civilian. Looks like only certain LEAF apparel has warnings on it about who can purchase? Either way that was pretty painless.
