In Italian, senza translates as "without," as in, you'll never want to be without Castelli's Senza Jacket. It gives you protection from weather without bulk thanks to the windproof, water-resistant Windstopper X-Fast fabric; plus, the Flip-up Thermoflex collar keeps rain and snow at bay. The Senza also features high-loft fleece for insulation. The full-length Camlock zipper gives you plenty of venting control, and a gripper waistband prevents drafts and bunching. A zippered rear pocket holds small essentials, and the three larger rear pockets are ideal for food and a spare tube. Enjoy those long rides—even when it's cold—with the Senza.
