The Rab Neutrino Vest is a superb lightweight vest. It is Ideal for backpacking in spring and autumn and for those cooler evenings year round. Pertex Quantum fabrics keep weight and pack size down and 120 g (Large) of 800 fill Hydrophobic European goose down provides fantastic warmth for the weight. A stalwart of the Rab range for many years. This is a great piece for active use and for travel where weight and pack size are prime concerns.
