This is one of the best cold weather tights I own, period (later on the straps). The materials are extremely nice to touch on the inside and outside, they are warm even in sub-zero temperatures; fit is great once you figure out Castelli sizing. I live in Canada and ride these mostly from -6C to +8C. They remain warm in sub-zero temperatures as long as there is no real wind; on windy days you start feeling the cold, and would recommend switching to Sorpasso RoS tights. The fit is tricky with Castelli; I'm 180cm 76kg and XL fits me well. Now, the only disappointing point for these tights is the straps: unfortunately, they bunch up and become uncomfortable on longer rides. I wish Castelli would make the effort and use the same straps as on Sorpasso RoS tights.

I've been using these tights for winter riding and they didn't disappoint. They feel great, the chamy is as good as it gets, Castelli high quality. Been using these for sub zero temperatures (-6C) as well and they have been great as long as it's not too windy. For above zero temps they are just great, keeping you warm and cozy even when windy. For below zero I found them fine as long ae it's not windy; with a bit of wind you start feeling the cold especially in the front area. Overall, great cold weather tights!!

I'm running these at freezing point (0*) in Finland, in threshold workouts, and in base (Zone 2) rides. It feels warm from from the start. No sweat accumulation inside. Flexible at knees. Stretchy material sits pleasantly tight on body, with no any jamming. Size XL fits well on my 186 cm 88 kg. For reference, my other bibs are Entrata 2 size XL. So I highly recommend these tights for autumn/winter. Haven't tried in rain yet, though.
