Horses for courses....
As long as they have a comfy wide flat band at the waist( no rubbing under hip belt) & around a 6" inch inside leg (to stop chafing), I'm happy.
Tropical climes...synthetic micro mesh, airy & quick drying.
Subtropical....synthetic, quick drying
Temperate climes...synthetic again, I just change into thermals at beddy byes.
Synthetic can get stinky on longer hikes so rinse when you can.
Paw paw ointment works wonders if you ever do get that burning chafe that makes you walk funny to ease the pain.
