The Morobbia Alpha Vest is a perfect companion that protects and warms in bad weather while remaining breathable. The secret lies in the Pertex® Quantum Air outer fabric, a completely innovative material that creates a unique barrier. It is completely waterproof, yet air can pass through the fibers. This ensures a consistent temperature when you are riding up a long mountain in adverse weather conditions. The Texashield Core Stretch inserts provide optimal freedom of movement, while the Polartec® Alpha insulation keeps you warm without adding bulk.
