Several major manufacturers of outdoor clothing offer such clothing, but I couldn't find any at my local outfitters. I turned to online vendors, and I outfitted myself with an ExOfficio Bugs-away Halo shirt and a pair of Columbia Bug Shield Cargo Pants - Both utilized Insect Shield treatment. I wore those thru several sections of the AT and experienced no ticks, nor any mosquito bites on areas covered by the fabric. I did have a tick latch on to my sock and crawl down inside.
I hadn't heard of Insect Shield treated socks ...
