TENAX 4 is the result of 2 years of planning and testing carried out in collaboration with Alex Ploner and Christian Ciech, Italian team pilots and multiple world champions. The harness has been designed to meet the needs of the most demanding pilots in terms of performance, and is ideal for competitions.
Its low drag and its characteristic geometry enhance flight performance.
A very high level of comfort that you will appreciate especially on long flights has been achieved with the new ergonomic, enlarged shape back board.

The location and deployment of the rescue parachute has always been key for all our harnesses.
This means our pilots must be able to deploy easily and quickly regardless the hand they use in that moment.

The location of the rescue parachute container varies according to the harness size without compromising the overall aerodynamics of shoulders, arms and pockets. As a matter of fact, the rescue parachute stays partially inside the harness on the pilot's back just like in our Tenax3.

All the straps that form the bearing structure of the harness and wrap around the pilot are interconnected, including the harness bridge connections for emergency parachutes, positioned behind the shoulders to ensure a more vertical pilot position in the event of parachute opening.

TENAX 4 is available with four possible in-flight incidence change systems:

(see manual for further details 3.1.1)
(see manual for further details 3.1.2)
(see manual for further details 3.1.3)

Main frame

The harness main frame is rigid in the middle and softer along the sides. The main zip is equipped with Velcro and therefore it is easily changeable.

Back board

Our new back board is as long as the previous model but double wider, this is to ensure as much comfort as possible and avoid pressure on the pilot even during long flight
The back board is made with carbon and Kevlar and the distinctive central rib makes it extremely resistant against high levels of stress.


The harness skin is the second most important improvement after the new back board. The skin is made with a light and strong rip-stop fabric that is completely detachable and therefore easy to clean, repair and even replace (which means we will offer such skin as spare part, eventually)


The new tail cone is longer than the previous model to ensure even better aerodynamics, it will come together with combinable five-centimeter gauges so the suitable harness length can be set without having to adjust the shoulder straps.

Sistema recco

Il rilevatore RECCO® emette un segnale radar paragonabile al raggio di luce di una torcia.

Quando il segnale radar colpisce il riflettore RECCO®, questo lo rimanda al rilevatore e indica al soccorritore la strada per raggiungere la vittima.
