I think you may be a bit confused. there is a base that BA designed as an exercise base. it is not all lace. then there is another base that you can order that is all lace...not specifically designed for exercise but can be worn any time.
there is no such thing as "exercise lace", I think you are referring to his base design called exercise base. it has both lace and thinskin I believe. you may want to check by emailing john at <!-- e --><a href="mailto:[email protected]">[email protected]</a><!-- e -->
hope this helps.
