SIGMA II
In the realm of engineering, “Sigma” signifies a culmination or solution to challenges.
We proudly dubbed our latest tandem system Sigma II, embodying all we’ve learned about tandem equipment and its users. After extensive development and rigorous testing, the Sigma II Tandem system has emerged as our most robust and secure offering to date.
Your feedback guided us every step of the way. Featuring an exceptionally comfortable harness and an elevated free-fall position for instructors, alongside the student harness designed for maximum comfort—this setup is unmatched. With newly designed, military-grade ballistic leg pads, VGH articulating harness, retractable release handles, easy component replacement options, and our originally patented Disc Release system matched with the all new patented TB Pulley Release design—we’re setting new and even higher standards in safety and convenience.
Constructed for durability and fatigue reduction, the Sigma II feels more like a sport container than mere work gear.
