Anyone comment on tights vs. baggy shorts for touring?
Tights are good in cool or cold weather.
If you mean lycra, spandex, etc., vs. baggy shorts, wear whatever you're comfortable with.
Some people imagine they're being checked out every moment someone else can see them, and they feel shy. I think of bike shorts as activity-appropriate gear. You wouldn't wear golf pants at the swimming pool, or a swimsuit on the golf course. Conversely, most people wouldn't look askance at someone wearing bowling shoes at the bowling alley. I'm comfortable wearing bright jerseys (for good visibility and breathability), and cycling shorts (for support and to minimize chafing), when I go out for a bike ride. If you're not comfortable doing that, you can wear whatever you want, or you can carry something to slip on whenever you get off the bike.
