The latest generation of our proven ultralight harness – further developed to meet the highest demands in Hike & Fly and mountaineering. Thanks to a new inflatable protector, improved speed system and two sizes, the STRAPLESS 4 is now even more versatile – without compromising on weight, comfort or simplicity. The STRAPLESS 4 is now certified up to 120 kg.
INCREASED OVERALL COMFORT
Important optimisations have been made to the STRAPLESS to make the seat shape more ergonomic and significantly increase overall comfort. In addition, the ultralight harness features a new accelerator routing for improved pressure distribution and more accelerator travel.
INFLATABLE AND LIGHT
Alongside the STRAPLESS 4, we are launching ADVANCE's first inflatable protector, which is an optional extra. It weighs just 220 g, which is exactly the same as the STRAPLESS 3 airbag, but offers protection right from the start.
