The Sorpasso RoS Wind Bibtight sits right at the top of Castelli’s long-legged offerings, both in terms of cost and claimed warmth. These aren’t ‘Shall I wear leg warmers or tights today?’ kind of bibs, but more the ‘Can I get to the bike shed through the snow drifts?’ kind of bibs. The RoS in the name stands for ‘Rain or Shine’, but I definitely would not want too much of the ‘Shine’ when wearing these unless it was of the freezing alpine sort as they are rather warm.
They are designed for riders who go out whatever the weather, be they committed commuters, dedicated trainers or just hardcore cyclists who prefer to avoid the turbo trainer at all costs. Castelli rates them for use down to -5°C, although I imagine they would still work in temperatures below that. The upper suggestion is for +8°C, and that seems fair, although at that temperature you wouldn’t need to be working very hard to be pretty warm indeed. Currently only available as part of the men’s range in black, sizes S to 3XL.
