Bib. Pearl Izumi for me. Chuck baggies over the top for the mtb.
If you have a but of a belly, they also tone down the bulge as well, not that I’d know!

Santini Slice from Prendas are the comfiest I’ve worn – mesh back/sraps, low cut at front and two pockets in rear.
“Italian” cut so not going to fit everyone, but Prendas are pretty good at sizing you if you fill in their “vital stats” form….

Bibs of various lengths for all seasons, loads more comfortable & you don’t end up wi yer bike rack on show!
