Castelli’s Sorpasso RoS (rain or shine) bib tights are designed for temperatures ranging from 0°C to 12 °C / 32°C to 54°F and they have become one of my favourites for changeable conditions.

They utilise Castelli’s third-generation Nano Flex fabric, which does an excellent job of beading road spray and rain. You’ll remain comfortably dry for a few hours because breathability is better than hardcore waterproof tights.

The rear uses the X-Dry version of Nano Flex. Its coarser surface helps grip the saddle and it’s much more abrasion resistant and so avoids premature wear or bobbling.

The Progetto-X pad is comfortable but not bulky. The shaping of the legs by using multi-panels front and back adds freedom. And keeping seams away from areas of potential chafing – behind the knee, for example – is a neat touch.

The full bib and legs are fleece-lined to beat the chills and I’m also a fan of the high waist for protecting your midriff, while the broad braces and mesh panel keep things firmly in place. The 19cm zippers on the ankle have a 3cm wide reflective strip for visibility.

With these bibs designed with training performance in mind, I’d recommend sizing up one from normal.

All in all, the Sorpasso RoS bibs deliver everything I’d ask from winter tights.
