Sigma SR Reserve Canopy

Sigma II Reserve is available in two sizes: SR340 and SR370. Improvements to the Sigma Reserve design compared to VR-360 include: ease of packing, improved opening characteristics, and better performance in flight and landing characteristics. Designed with ease of packing in mind, we introduced a cascaded Vectran line set, which allows this reserve to have an overall lower pack volume than the VR-360.

Further, UPT has implemented color alternating line tabs to make line groups easily identifiable. The opening characteristics take into account the wide range of possible deployment speeds, and give an opening that meets the altitude or time loss requirements specified by TSO-C23f, while still maintaining a comfortable inflation for the jumpers. Once open, the Sigma II Reserve flies and lands more similarly to a tandem main parachute. It has a slightly flatter glide than the VR-360, intuitive controls that allow for ease of turning, and a deep control range to reduce the likelihood of stalls.  The Sigma II Reserve is designed to minimize toggle effort while maximizing the flare power on landing.
