The Castelli Velocissimo 5 Bib Tights are the ideal cycling tights for almost all your winter riding. Focussed on performing best in mild to cool conditions the bib tights have a minimalist design that is big on performance, offering superb comfort and splash protection.The Velocissimo Bib Tights use Castelli’s Thermoflex fabric in the upper section for immediate and long-lasting comfort. This fabric is perfect for temperatures around the 10°C mark and is Castelli’s softest, stretchiest winter tight fabric.Below the knee the tights use Castelli’s Nano Flex fabric. This fleeced fabric is both highly warm and splash resistant, protecting your lower legs from spray in the damp conditions that characterise much of the cooler months of the year in the UK. The fabric is also highly stretchy, so Castelli has been able to construct the ankles without zips to minimise bulk whilst making sure the tights are still easy to put on and take off.The Velocissimo tights use Castelli’s KISS Air2 seat pad. This pad offers just the right amount of padding whilst maintaining great moisture management properties. Favoured by many of the pros, it is slightly less voluminous than the Progetto X2.Key FeaturesThermoflex fabric from knee to waist for warmth and comfort,Nano Flex at lower leg for splash protection,KISS Air2 seat pad,Mesh bib straps,Zipper-less ankle to reduce bulk,Reflective inserts on thighs,8° – 16°C / 41° – 61°F,Weight: 241g (M).
