Skinsuits from Castelli for men combine jersey and bib shorts into one garment with no waistband at the join.
Castelli skinsuits for men
Without a waistband, the chamois pad stays in position regardless of your back posture, no folds form around the stomach, and the fabric flaps less in the headwind. In time trials and triathlon this is measurable, at touring pace less so.
Many models have a long rear zip. It does not remove the drawback completely: a toilet stop takes longer in a skinsuit.
Tip: If in doubt, choose the colour you combine most often. This makes your kit more versatile.
