Reserve weight 0.9-1.2 The QUATRO LIGHT is our ‘1% reserve parachute’. It weighs only 1% of the maximum certified payload (sizes 90, 110 & 130) and combines fast opening, stable descent and low sink rate. QUATRO LIGHT is the number one rescue parachute in our range for travellers, hike & fly pilots and for all those who closely focus on the weight of their equipment.
