The Rev’It! Excalibur jacket is a great choice for any rider looking for a versatile, four-season performance piece. It features a removable thermal liner as well as a removable waterproof membrane, which provide significant insulation from the elements, and also can be removed and worn together as a separate jacket. When both the thermal liner and waterproof membrane liner are removed, the jacket offers the excellent ventilation of a summer jacket. Additionally, those who regularly ride in hot weather can upgrade the jacket with a Challenger cooling vest insert, which connects with the same zippers used to secure the waterproof membrane. Although it has the clean lines of a seemingly simple design, the Excalibur is a capable performer.
