Leading edge bladder only Noise Pro Version 2.
The most obvious difference between the V1 and V2 Noise Pro kites is the inflation valve. The V1 has the old school 9mm, beach ball style, inflation valve. The V2 has a black Boston, screw on, inflate/deflate valve. There is no way to retro fit a V2 Leading Edge Bladder onto a V1 kite.
