It’s a vicious circle. You get a warm jacket, then sweat when you ride, get wet and cold then get an even warmer jacket. Many cyclists get cold because they’re overdressed or don’t have enough airflow to keep them dry. That’s what makes the Castell Mortirolo 3 Windstopper Jacket ideal for so many riders. The Windstopper X-fast on the front and sleeves keeps the cold at bay, while the warmer back allows massive breathability. You’ll stay drier and, at higher intensity levels, possibly warmer than with a full-protection jacket. It’s no wonder this is a top seller every year.
