The Omega 4 is a paraglider circa 1998.

The high-performance Omega 7 glider from the Swiss factory has been certified in DHV2-3 class and is based on the World Champion prototype. The Omega 7 has a noticeable high arch of the canopy that makes it “inherently more stable and able to be flown faster without collapsing, even in turbulent air”, according to Advance. As a result, the Omega 7 also has a significantly higher aspect ratio than its predecessor for higher performance. It also incorporates a “carefully calculated” profile and competition lines. The manufacturer claims a glide ratio of 10:1 and an “exceptional glide angle” in the upper speed range, plus the “familiar, direct Advance handling”. The Speed Performance Indicator (SPI) also helps experienced pilots to choose the optimum speed. The Omega 7 is equipped with a variable transfer speed system that enables shortening or lengthening of the speed bar extension range and pressure to suit the user’s anatomical position. This new model is the first to feature a new fabric developed exclusively for Advance in collaboration with Porcher Sport as well as special coated lines developed with Liros, UV resistant. Other details include sewn-in compression and Mylar straps for better stability of the canopy, partially closed cells for higher internal pressure, winglets to reduce drag (vortex effect), velcro closures on the wingtips to remove debris from the glider, swivels on the steering lines, and different brake handles with magnetic clips depending on the canopy size. The Omega 7 was available in 4 sizes and 3 color schemes.
