This has been flown 4 times. My previous harness was the Avasport Acro XL so I ordered this in an XL and it turns out they changed the sizing on this new model. The seat board is about 6cm longer than previous model XL. It will fit someone who is 6'3" or taller. It's an incredible harness. 2 under the seat reserves plus the base cutaway. This is the pinnacle of evolution in acro harnesses. No sketchy metal pins for the reserves. Perfect harness in my opinion, I just need a size smaller. Ships from Utah, USA. Shipping not included.
