The LM4 is a simple answer to a request that we received many times after the release of the Mantra M4. The world’s most experienced Vol-Bivouac / Adventure pilots wanted a lightweight wing with top of the line performance.

The LM4 top surface is constructed from Porcher Skytex 36g classic. This is the same cloth we have been using for years in the Geo and Swift series. This cloth has mechanical properties similar to a 40g cloth as it has the same structural ripstop. It has been proven reliable over the years and is the best light cloth available for the top surface.

Porcher Skytex 27 classic makes up the bottom surface, and we believe this is the best ultra-lightweight cloth available. Used for the Swift, the UltraLite, and also in the R10’s, the Skytex 27 classic is not only very light, it has proven to be strong and to last well when used in the right areas of the wing.

The ribs, diagonal ribs, and straps are made from Porcher Skytex 40 hard and Skytex 27 hard. The longevity of the structure cannot be compromised and therefore only the parts with very reduced stress are made with the 27g.

The standard risers are made from 12mm cousin webbing with stainless maillon rapide links, and the light risers are made with 8mm dyneema webbing and LinkLite connectors, for a savings of about 200g.
