I live in a city, so it's not like I'd be running down some country road by myself. I'm committed to the split shorts, so shirtless I'd be almost naked. I'm in my 30s, but I'm fit. I've been running with my shirt on, but it's hot. I also track heart rate, so I'll have a strap across my chest.
Should I run shirtless or buy some singlets? If singlets, does any one have any recommendation for some cheap ones I could buy multiple colors of?
