Strapless 4

STRAPLESS 4: ULTRALIGHT MOUNTAINEER

Comfort and ergonomics: 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.

Optional protector: Inflatable and Light

Alongside the STRAPLESS 4, Advance is launching ADVANCE’s first inflatable protector, which is available as an optional extra. It weighs just 220 g — the same as the STRAPLESS 3 airbag — but offers protection right from the start. Installation is very simple and is done using six bullet toggles.

Innovative Flowbag: Easy Inflation

Inflation is easier than ever before thanks to the new FLOWBAG inflation bag, which weighs just 33 g. Just under two FLOWBAG fillings are needed to fill the protector completely. To reach the volume in the FLOWBAG, it is sufficient to blow lightly into the bag twice — it couldn’t be easier.

Alternatively, the protector can also be filled directly via the tube, but for hygienic reasons we recommend using the FLOWBAG, which is delivered with the protector as standard.
