Some argue that it is the most difficult climb in professional cycling and some avoid it altogether. Nevertheless Castelli designs Mortirolo gloves after an infamous bike climb and takes inspiration from mixed weather which usually happens on mountain roads. Made from Gore-Tex Infinium Windstopper fabric which provides windproof and splashproof protection from approaching clouds and fog , Mortirolo is designed for that to easily withstand temperatures of 45–59 degrees Fahrenheit. Silicone grip allows you to confidently hold the steering wheel even on wet roads and the convenient back-of-the-hand zipper is easy to use when stopping at a café near the top.
