Advance Easiness 4

The Advance Easiness 4 is a lightweight reversible harness — three sizes covering 155–202 cm pilot height, weights from 2.10 to 2.20 kg (up to 200 g lighter than the Easiness 3), EN & NfL certified to 120 kg. Built around an extended back support and side panels that make it noticeably more comfortable on longer thermal flights than past Easiness generations, while staying packable enough for hike & fly and travel.

The two big in-flight comfort upgrades are the extended back support, which improves seating comfort across both normal and accelerated flight, and the new side panels — these reduce wind chill noticeably on cold or long flights, where the previous generation got drafty. Weight savings come from targeted material and construction choices: notably, the rucksack mode no longer needs a moulded back panel — the packed glider itself provides the structural tension to hold the rucksack shape, which makes the pack lighter, less bulky, and rides closer to your back for better weight distribution. Carry features are well thought out: wide Velcro shoulder straps, an external helmet net, zippered hip pockets for quick access on the trail. In flight, a zippered side pocket adds storage that's actually reachable mid-air. Rucksack volumes scale by size: 46 L (S), 50 L (M), 58 L (L).
