Flybubble Note: Ultra-light gear must be handled with care to extend its lifespan. Mechanical stresses and improper handling can cause faster wear and tear compared to standard-weight gear. Designed for hike and fly activities, ultra-light gear prioritizes weight savings over durability and other factors. To avoid damage, refrain from extreme activities or excessive ground handling. Gentle treatment is crucial for longevity and safe operation.
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.
Features
- Two sizes (M and L): for a better fit and wider target group.
- New inflatable protector: ultralight (220 g), easy to use and
optional. - Improved speed system: for more comfort across the entire
acceleration range. - More ergonomic seat shape: thanks to 3D shaping and optimised
legpads. - Edelrid AURA carabiner: with new Anti-Twist LITE element.
