I kind of went full-on roadie since my post here two years ago.
I'm now up to 6 bib shorts (mix 'n' match designs), 1 bib shorts that's part of a matching kit, and 2 thermal bib leggings. I also have 4 regular (waist) shorts, but those are primarily used under other clothing for longer transportation rides, or under winter gear when it's too cold for thermal leggings.
I ride nearly every day, sometimes twice a day (transportation and recreation), so the collection makes sense to me!
