Take the Perfetto RoS Long Sleeve Jacket, add the Sorpasso RoS Bib Tights and what you have is the brilliantly warm and protective Castelli Sanremo ROS Thermosuit. A one-piece suit created for the most dedicated of winter cyclists.

So why exactly would you want the one-piece Sanremo ROS Thermosuit as opposed to separate garments? Well, it all comes down to boosting comfort. Removing bib straps and extra layers around the waist keeps the fit flexible, snug and warmer too, all improving comfort when the weather takes a turn for the worse.

Warm Body

Starting with the top, this is the Perfetto RoS Long Sleeve jacket. Made from Castelli-exclusive Gore-Tex INFINIUM™ WINDSTOPPER®, water-resistant and insulating Infinium 205 is used for front-facing panels to keep out the elements. Meanwhile, back panels benefit from the extra breathability and stretch of Infinium 203. Taped seams at the shoulders prevent water ingress and zipped chest vents allow you to dump heat if you find yourself warming up during more intense efforts. 

Supple Legs

To the legs, the construction is based on Castelli's superb Sorpasso RoS Bib Tights. This sees the use of Nano Flex 3G fabric to give the ideal mix of warmth, stretchy muscle compression, luxurious softness and water-repellency. Meanwhile, the thighs and upper-front panels are made from extra-warm Nano Flex Xtra Dry fabric, locking in body heat and locking out cold temperatures. The anatomic cut over the knees and hips ensure the perfect fit and smooth pedalling too. And with training often getting done as the daylight fades, reflective panels at the ankle offer up maximum eye-catching visibility when darkness descends. 

Put it all together, and everything works to perfectly regulate your body temperature, fend off the harsh winter elements, keep muscles supple and keep you comfortable on the bike come rain or shine.
