Bib tights are fantastic for winter riding -
they cover from ankle to belly button,
feature comfortable chamois,
and an insulation layer inside that
helps keep your legs and core warm.
Some models (Santini Lava and Nimbus)
have very good reflective strips down
the calf for added visibility in low light.
As well, Nimbus has a rainproof layer for
protection against the winter rains.
