Clear summer days in Alaska are beautiful, but often times disrupted by swarms of bugs. Look closely at the picture below and you can see what I mean. Notice the swarm around my head? Without a head net, the bugs (mainly no-see-ums and mosquitoes) will crawl into your nose, ears and mouth. They quickly become very annoying. It's a great setting to try out the bug repellent, ExOfficio Insect Shield fabrics.
