Who rides with their jersey's undone/fluttering in the wind?
Over the past couple of days while riding out on the bike, I've seen more and more riders riding with their jersey's undone and fluttering in the wind behind them. This give me, the oncoming rider, a good view of their heart rate monitor (if they are using one) and bib straps.
I'm good/comfortable riding with my jersey done up (maybe I don't get that hot?) but what's the consensus here? Yeah, on a hot day why not? Or no, don't unzip ever?
Curious to hear thoughts. Cheers.
