For mountaineers, Hike & Fly pilots, and weight-conscious adventurers, the new ADVANCE STRAPLESS 4 sets a new benchmark in ultralight paragliding harnesses. Weighing just 235 g (M size) and offering significant ergonomic and safety upgrades, this fourth-generation model delivers maximum performance with minimum weight.
Whether you're climbing peaks before sunrise or descending remote ridgelines at sunset, the STRAPLESS 4 offers the comfort, safety, and simplicity that experienced mountain pilots demand.
Precision-Made for Mountain Pilots
ADVANCE is known for its Swiss precision and dedication to quality, and the STRAPLESS 4 continues this tradition. It's not just lighter — it's brighter, safer, and more versatile.
Key innovations include:
-
Two sizes (M & L) for an improved fit and broader usability
-
New inflatable protector (optional) offering protection from the start of flight
-
Ergonomic 3D-shaped seat with optimised leg pads
-
Redesigned the speed system for smoother accelerator travel
-
Edelrid AURA carabiners with Anti-Twist LITE system
This makes the STRAPLESS 4 an excellent choice not only for ultralight enthusiasts, but also for ambitious pilots flying extended routes in alpine terrain.
Optional Inflatable Protector: Lightweight Safety
For those seeking added safety without compromising weight, ADVANCE offers its first inflatable protector, weighing just 220 g. Installed with bullet toggles and inflated using the included FLOWBAG (33 g), it provides instant protection — unlike traditional foam airbags that only inflate after takeoff.
Combined with the harness, carabiners, accelerator, and protector, the complete set weighs only 580 g — a serious advantage on long ascents.
Designed for Comfort and Simplicity
Despite its minimalist build, the STRAPLESS 4 is comfortable even on longer flights. The new seat shaping, front strap geometry, and accelerator routing offer improved pressure distribution and easier launches. Pilots benefit from adjustable shoulder straps, an accelerator holder, and step-in aids, all crafted with practical alpine use in mind.
