The SIGMA DLS from ADVANCE represents a significant step forward in the XC sports-class paraglider segment, targeting seasoned pilots looking to upgrade from high-B wings without moving into the demanding high-C or D categories. With its placement in the EN/LTF C segment, it aims to blend impressive performance with accessible, forgiving handling that makes cross-country flying enjoyable and approachable.
At the heart of the SIGMA DLS is a combination of innovative design and proven technology. The wing features a new airfoil and nitinol-reinforced front mini-ribs, which ensure a clean and stable leading edge. This design enhancement significantly improves profile fidelity and glide performance, especially at higher speeds and in turbulent air conditions. The moderate aspect ratio of 6.1, combined with a 3-liner configuration, balances performance gains with safety reserves, making the glider suitable for pilots with conventional C-class skills rather than specialists only.
Durable Lightweight Structure (DLS) and Build Quality
A standout feature of the SIGMA DLS is the Durable Lightweight Structure (DLS), which uses a strategic blend of Skytex fabrics (27, 32, and 38) rather than opting for an ultra-light but fragile material. This approach ensures the wing is both light (starting at only 3.7 kg) and robust enough for regular XC flying, hike-and-fly adventures, and travel. The use of super-elastic nitinol rods furthers benefits by reducing pack volume and resisting permanent deformation—practical advantages for pilots who frequently pack and compress their gear.
Advanced Riser System and Lines
The SIGMA DLS’s riser system includes an effective pitch-control mechanism with C-handles, facilitating precise control from the C- to B-level lines. This arrangement helps maintain wing profile and speed during active speed-bar flying in turbulent air, allowing pilots to exploit the wing’s full speed potential without significantly compromising airfoil integrity. Complementing this is the use of Edelrid Pro Dry unsheathed lines, which are length-stable and highly water-repellent, preserving performance consistency over time and in humid conditions.
Flying Characteristics and Pilot Feedback
Surveyed test pilots and the ADVANCE team consistently describe the SIGMA DLS as having playful yet precise handling, favoring active thermalling and clean turns. It reportedly offers easy launches and very stable full-speed flight, delivering what has been called "the best handling of a SIGMA ever." Pilots have undertaken impressive cross-country journeys exceeding 400 km on this wing, highlighting its capacity to inspire confidence and engagement over long distances.
Size Range and Weight Recommendations
The SIGMA DLS is available in five sizes spanning flat areas from 20 to 28 m², supporting certified takeoff weights from 57 kg up to 128 kg. ADVANCE's innovative 'Seamless Weight Ranges' strategy means each size's ideal weight band minimizes overlap to channel pilots into the most optimal size for their weight. All sizes maintain consistent aspect ratios and cell counts (65), promising predictable behavior across the range.
Customer Reviews and Market Reception
Although the SIGMA DLS is relatively new to the market, initial customer feedback is positive, albeit limited. The sole publicly available review expresses complete satisfaction, stating the glider meets expectations and complimenting swift and reliable delivery. Dealers and retailers emphasize the wing's lightweight nature and performance leap over preceding models, aligning with the one pilot's direct experience.
Shops highlight the DLS construction and nitinol rod benefits as key selling points, underscoring the wing’s durability and packability. While long-term durability and detailed in-situ pilot feedback on rough air handling and collapse behavior remain to be seen, no negative build quality reports have surfaced, consistent with ADVANCE's strong reputation.
Considerations Before Purchase
Prospective buyers should note that the wing remains classified as EN/LTF C, demanding solid active flying skills, SIV training, and consistent thermal XC experience. Because independent pilot reviews are scant at present, hands-on trials and consulting experienced instructors or local XC pilots familiar with the Sigma series are advisable. Monitoring for future detailed pilot reports will be essential for a comprehensive understanding.
Summary
The ADVANCE SIGMA DLS offers an attractive package for experienced XC pilots seeking a high-performance, yet manageable, EN C-glider with a focus on lightweight construction and durability. Its innovative materials and design features promise superior glide and handling characteristics, supported by an emerging body of positive pilot testimony. However, buyers should approach early customer feedback as initial signals rather than definitive proof, complementing it with practical demos and expert advice.
