As everyone else has said already, excellent thread title lol
About boxer briefs, I got a few pairs from Old Navy recently and they are awesome. They keep their form throughout the day (legs don't get baggy) and I can pack in them without having to worry about anything falling out of place. Soft and comfy too, can barely feel them. I prefer to pack but hate having to wear additional "equipment" to keep things in place so this was a great solution for me. Really, any pair of boxer briefs that stay snug are great for packing.
Ahh, leg hair. One of my favorite things about summer is wearing shorts and having the leg hair out and proud.
