ADVANCE Lightness 3 M — A Light Seatless Harness With Superb Back Comfort and Finish

Choosing the Lightness 3 means giving up the quick reactions of a seat harness in return for back comfort and low weight. If most of your flying is long XC with hours in the harness, that trade is worth making. Pilots who want to work a high-aspect-ratio glider finely through their lower body are better served by a seat harness. And if you plan to move your current reserve across, check its size first, because the compartment runs small.
