The MOROBBIA ALPHA VEST is a perfect companion that protects and warms in bad weather, but is still breathable. The secret lies in the PERTEX® QUANTUM AIR outer fabric, a completely new material whose weave forms a unique barrier. It is completely waterproof, but air can pass through the fibres to the outside. This ensures a constant temperature when you are travelling up a long mountain in adverse weather conditions. The TEXASHIELD CORE STRETCH inserts offer you optimum freedom of movement, while the POLARTEC® ALPHA insulation keeps you warm without weighing you down.
