LIGHTNESS representa una silla reclinada con carenado, extremadamente ligera y muy cómoda, junto con su propia mochila ligera. Ambas van perfectamente juntas y estos productos de calidad pesan sólo 3 kg en total, formando una entidad compacta. La LIGHTNESS es más adecuada para pilotos senderistas orientados al vuelo de cross, viajeros o amantes del vuelo vivac.

Probada y testeada en el X-Alps
El concepto único de la LIGHTNESS lleva plenamente el espíritu del X-Alps con él y personifica la idea original del vuelo libre –obtener los metros necesarios a pie y luego aprovechar al máximo su potencial en vuelo. El equipo X-Alps de ADVANCE sometió a la LIGHTNESS a una verdadera y exhaustiva prueba y Chrigel Maurer ganó la carrera de parapente más dura del mundo con ella.
Máximo nivel de comodidad– en el aire y sobre el suelo
Esta silla no lleva tabla de asiento y por lo tanto se ajusta al cuerpo perfectamente. El cómodo principio de la hamaca consigue dar una respuesta aún más directa del ala al piloto. Sus muchos ajustes se utilizan para acomodar el arnés con precisión a los requisitos individuales y, por ende, todo el cuerpo recibe un soporte ideal. La mochila excepcionalmente compacta también ofrece el más alto grado de comodidad en el transporte.
Ligera y sofisticada, sin compromiso
Gracias a la calidad de acabado demostrada en materiales ligeros de la más alta calidad y un concepto convincentemente simple, la silla con carenado, contenedor frontal, porta instrumentos y espuma de confort pesa sólo 2,3 kg; la mochila, alrededor de 700 gr. El sistema LIGHTNESS, por tanto, puede compensar el peso de un parapente normal. Esto significa que, sin recurrir a una vela ligera, todo tu equipo puede llegar a pesar apenas sobre los 10 kg - casco y paracaídas ligero incluido.

Los componentes de la ADVANCE LIGHTNESS se han desarrollado con un decisivo acento en el bajo peso, y están dirigidos a usuarios especializados. Esto, indudablemente, pone altas demandas en su uso y cuidado, que hace esencial un completo entendimiento del producto y sus cualidades. Debido a los materiales escogidos y su construcción, la mochila y la silla son definitivamente más susceptibles al desgaste resultante de un uso inadecuado que los productos ADVANCE normales.

The LIGHTNESS is just as comfortable as an IMPRESS, otherwise Chrigel Maurer couldn’t have made his ten hour flights during the X-Alps and the preparation for it. The biggest difference is the weight. A LIGHTNESS M harness weighs 2.3 kg, an IMPRESS 2 M a little over 7 Kg. The LIGHTNESS pilot pays for the 5 kg difference, however, with somewhat less user-friendliness, less protection and a shorter lifespan:
- Less user-friendly, because most of the adjustments cannot be made in the air, and the reserve can only be carried in a front container.
- Less protection and safety, because the LIGHTNESS harness has only a thin and small comfort foam.
- Shorter lifespan, because of the lighter materials used. They do indeed show very good robustness for their weight, but when it comes to long life, resistance to wear and UV they will not come close to the value of normal materials.
-
The LIGHTNESS works like a hammock, which fits the body perfectly. The remarkable compromise of low weight and high comfort was mainly achieved by using this concept. Chrigel Maurer flew countless kilometers with flights of up to ten hours duration during the preparation phase of the X-Alps project. This hammock principle also gives the pilot even better feedback from the wing.
-
The components of the LIGHTNESS were designed and built with the focus on minimum weight, down to the last detail. The development target was to use as little material as possible and seriously question the inclusion of every gram. Often a bewilderingly simple solution emerges when the debate is over – like, for example, the hammock principle for the seat surface of the harness, with no seatboard. On the other side of the equation uncompromisingly light materials were used. The speedbag for example is made from high quality, elastic and abrasion-resistant fabric, normally used for practical outdoor clothing - mainly trousers.

The harness and the rucksack go well together and make a compact unit. The full potential of these products can only be realised when they are used together. The interplay of harness and rucksack paid off perfectly at the X-Alps. Firstly the shape of the rucksack is matched to the harness so that the equipment can be packed very compactly, and the weight lies close to the hiker’s back. Secondly the back pocket of the harness is exactly tailored to the rucksack for a perfect fit. A normal bigger and stiffer rucksack would be a nuisance for the pilot in flight, and leave less room for clothes, supplies, sticks etc. in the back pocket. Compared with a reversible harness however, where rucksack and harness are combined, the LIGHTNESS System has the advantage of much more versatility.
-
The compactness and geometry of the rucksack allows the one size to be carried equally comfortably by short or tall pilots. This is confirmed by the experience of the X-Alps - all three ADVANCE participants had identical rucksacks (Chrigel 183 cm, Heli 168 cm and Ramon 163 cm), even though they used different sized gliders and harnesses. Correct shoulder strap setting (adjustable for pilot height), hip strap adjustment and packing technique are important for carrying comfort.
Maximum comfort is only achieved when the rucksack is full and under light internal tension. This tension effectively takes on the function of the supporting frame of a conventional mountain rucksack (usually aluminium) without additional weight. The space inside the rucksack is mostly taken up by a suitably folded glider. The fine tuning at the end is automatically done by the comfort foam, which compresses when packed and expands in the rucksack to perfectly fill the space available. So the rucksack comes without compression belts, saving more weight.
-
Foot support in the form of a stirrup is essential because there is no seatboard. The speedbag therefore forms an integral part of the harness because the stirrup is built in to the speedbag for weight reasons.
-
The LIGHTNESS is a production version of the X-Alps harness used by the ADVANCE team pilots, in which every single gram was regarded as critical. A built-in reserve system would need extra parts, causing extra weight.
