I know you asked about clothing, but I feel compelled to tell you what has worked for me. I spray my complete outfit with Permethrin which includes boots, socks, pants, long sleeve shirt and hat. Bandana sprayed with Deet around neck and a squirt or two on exposed hands. Works like a charm every time. I carry a head net, but have never needed it with my current bug proofing set up. The best part is the Permethrin lasts about 6 weeks or 6 washings.
I just did a week long backpack trip at Isle Royale National Park and not a single issue with bugs. I would add our no-see-ums and ticks can be brutal in Michigan's UP.
