Ambitious Cross Country
The SIGMA 11 is, once more, one of the best performing wings of the C Class. The cross country Sportster has outstanding pitch stability as well as very precise handling. State of the art technologies such as 3X3D shaping at the leading edge and an efficient Pitch Control System with 2-liner feeling round off this product. ADVANCE quality lightbuild structure produces the SIGMA 11 from 4 kg.
A completely redeveloped profile gives the SIGMA 11 significant pitch stability. This results in not just a marked increase in performance in turbulence, but a much higher level of flying comfort on long flights. 3X3D shaping, reduced line surface area and a swept element to the wing planform are all further performance-enhancing features of this high-end XC wing.
The SIGMA 11 delights with its comfortably direct handling, immediately conveying the feeling of this wing’s sportiness to the pilot. Perfectly refined wing curvature and well-proven brake line geometry allows the XC Sportster to answer its smallest control input directly and precisely. This playful handling guarantees the best flying fun.
Weight-optimised internal structure means that a SIGMA 11 is available weighing only 4 kg, even though the outer wing surfaces are constructed of 38gm/32gm fabric. Ideal internal wing stress distribution design means that the wing does not have C-Wires on its upper surface, making it even more light and compact. Modified C level supports also improve extreme flight characteristics and raises the passive safety level.
The strongly curved and flow-sensitive area of the leading edge is now integrated by a triple graduation of 3D shaping. The result: a crease-free leading edge and smooth upper wing surface for clean airflow and more performance.
The low weight of the SIGMA 11 is primarily achieved by its sophisticated and carefully designed internal structure. Because the outer surfaces are still made of robust 40/38 gm cloth the light weight has no effect on the glider’s long life expectancy. The fabric used for the the SIGMA 11 is exclusively high quality cloth from Porcher Sports, the well-know European manufacturer.
The SIGMA 11 has an up-to-date Pitch-Control-System with C handles. This system transmits an element of C line input to the B line level so as to maintain an ideal profile shape. Even in accelerated flight the wing can be actively flown and steered by means of this C/B arrangement, giving a realistic two-liner feeling.
The SIGMA 11 is equipped throughout with colour-differentiated Pro Dry Lines from Edelrid. This latest generation of uncovered line is a further development of the highly respected 8000 Aramid line and has a 60% higher humidity exclusion factor. This line is extremely stable in length and demonstrates above-average resistance to failure after long use.

The SIGMA 11 size selection was thought of as having Seamless Weight Ranges between 10 and 15 kg steps. Every pilot’s flying weight will find itself within only one ideal takeoff weight range, because these ranges extend seamlessly through the glider sizes, but do not overlap. These SIGMA 11 ideal takeoff weight areas provide the optimal relationship between gliding speed and climb performance for each size in all normal flying conditions, and also take into account the different paraglider size characteristics.
"In summary, the SIGMA 11 is a truly fantastic sports wing—exemplary behaviour, top performance, and—for me, the most important aspect of all by far—a real pleasure to fly!..."
"We are blown away! The canopy is extremely clean, gives a confident, comfortable feeling in flight and can be controlled very precisely."
"The handling is a Dream. Extremely precise, agile, and the canopy gave me a very safe feeling, straight away – I couldn't avoid saying WOW!"
"First of all: this truly is a successful wing. Takeoff is super uncomplicated, centering in thermals is easy and on the throttle the SIGMA 11 is extremely stable."
