Flying at 2450 meters I had what felt like a collapse exiting a strong thermal lift. The left side of the wing lost pressure. Compensated by pulling hard left, but was a bit slow on giving the wing a chance to fly again. Too heavy hands on the steering. Sent me into a 360 spin and had to stall to gain control. After the paraglider was flying normally again I had a "cravat" on the right side which I worked on for a while to not enter a auto-rotation. Gained control and started to climb the thermal again.
The paraglider itself was a Ozone Alpina 2 ML with special lightweight risers, flown about 50 hours. Filmed with a Gopro Hero3+ and edited in Adobe Premiere Elements.
