This T-Magnum Jersey jacket from Astars has the look and feel of a jersey. The fit is extremely relaxed and ventilation is maxed out to keep the rider cool. The zip out liner adds a bit of flexibility, but keep in mind this a summer jacket. The size/fit are a bit more loose than most but the protection of CE approved armor is still there in the shoulders and the pre bent elbows, along with a foam back protector.
