Axess 4 Harness from Advance


SKU: N/A Categories: ,


AXESS 4 – Elementary Allrounder

The AXESS is the classic ADVANCE beginner harness, and this fourth generation is simpler, more compact and safer than ever before. Alongside the experienced Air-Foam Hybrid main protector we now have, for the first time in an AXESS, removable SAS-TEC visco-elastic soft-foam panels acquired from the world of motor sport. The packed harness volume and elementary features like Balance-Strap, Easy Connect and a natural adjustment system qualify this seatboard harness as an allrounder, where straightforward and trouble-free handling is important.

Advance Axess 4



The AXESS 4 has all the basic qualities needed for a beginner and allround harness. These range from easy adjustment, a plain and simple closure system, a safe and reliable riser clip-in procedure to the ease of sitting properly after takeoff – and the important standing-up-again before landing.

Simple and comfortable


The AXESS 4 is built to be robust. It has a seatboard, and the main protector is now joined by SAS-TEC crash protection. For a harness of this sophistication its packed volume is surprisingly small. When packing, the back section folds snugly to the seatboard, and the Air-Foam Hybrid-Protector also compresses when squeezed in the glider rucksack.

Fully-functioning protection


As its main protector the AXESS 4 has the removable ADVANCE Air-Foam Hybrid-Model – now in its third iteration. This protector was originally developed for the AXESS 2, and is ready for its full protecting function before any takeoff attempt. Visco-elastic SAS-TEC components are also installed at the sides and up the entire back. These defend the pilot against impacts and pointed obstructions.


Axess 4 Tech

Modern Air-Foam Hybrid-Protector

The Air-Foam Hybrid-Protector automatically fills with air when the rucksack is reversed into a harness, and under normal circumstances is ready to function after about 60 seconds. For maintenance it can be taken out of its own compartment under the seat shell. For maximum lifespan the protector should not be left compressed for extended periods, and never stored when wet.

Axess 4 Advance Technology

SAS-TEC Side Protection

Three visco-elastic soft-foam panels – one on each side and the other up the back – protect the pelvis and spine up to the neck. These protective components are made by the SAS-TEC manufacturer in Germany, and can be removed and replaced.
