I guess I don't understand - what is the difference between wearing a pair of shorts say 12 miles, hanging them up and wearing them again the next day?....and wearing one pair of shorts for a 50-100 mile ride? The risk of exposure, and/or whatever else could happen by wearing the same pair of shorts 2 days in a row would - I think - be doubled by wearing that same pair of shorts for a long ride due to increased friction, sweat, exposure, etc. I don't carry extra shorts with me on my commute and I'll do a lunch ride in 90-100+ heat and wear those same shorts for my commute home. I just view it as "resting" the shorts between rides coz on a weekend I would wear 1 pair of shorts for a 50+ mile ride in 90-100+ heat. I guess I don't see the difference but am open to opinions.
