Tracks not allowing 2 piece suits?

Just curious what you guys’ experiences are... I’m looking to buy full leathers, but was thinking of buying it in 2 pieces to allow me to occasionally wear Kevlar lined jeans, when I’m riding to work. I have heard that there are tracks out there that will not allow you to ride on the unless you have a full 1 piece leather suit. I just wanna know what your experiences are, as I’m not sure how to proceed. The pieces I’m looking at (Alpinestars) are a 360 degree zip as opposed to a 3/4 zip... via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/bk9sf9/tracks_not_allowing_2_piece_suits/?utm_source=ifttt
