Yes it is. Thats what I upgraded to.Is the large about the same size as the current JX3? Might be a good question for @kyler1945
I had both at the same time last season. The web(edit: medium) is narrower, I dont rememenr by how much, but it was noticeable for a guy with a 32" waist. In the end I sold the JX3, really based upon the seat width. I currently still have the web(medium).Is the large about the same size as the current JX3? Might be a good question for @kyler1945
