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.
