The Squadra Stretch Jacket is Castelli’s entry-level wind jacket, and it has been completely re-engineered to offer a simple and elegant solution than performs even better.The body and the front of the sleeves are now made from a coated ripstop nylon to keep the wind off your core and the most exposed sections of your arms whilst riding. The side panels and back of the sleeves are made from a tightly knit stretch fabric that provides the perfect close-to-body fit and introduces ventilation to the jacket so you don’t overheat or get that “boil in the bag” feeling.A high collar provides some welcome protection for your neck. Reflective details help keep you seen in low light. The jacket packs down small and will take up minimal room in a jersey pocket.Key FeaturesCoated ripstop nylon front and back and front of sleeves,Tightly knit stretch panels on sides and back of sleeves,High collar,Reflective details on chest and lower back,10° – 18°C / 50° – 64°F,Weight: 102g (M).
