Castelli Estremo WS Skully Cap

When you crest over the last little kicker into the flat and take the full brunt of a mid winter wind gust, you'll be glad to have your Castelli Estremo WS Skully Cap tucked warmly under your helmet. Panels of breathable Windstopper X Fast fabric on the front and sides boast a water repellent finish to fend off chilly wind and water, while cozy Warmer fabric adorns the rear. Recognizing that even having the tips of your earlobes exposed can cause ride ending discomfort, Castelli includes soft, warm, flip down ear panels for added protection when winter really sets in.
