Why this manual exists
Written by a sports engineer. Not a marketing team.
Mari Thomas-Welland used to test other brands' sports bras for a living. She, including the other women in her experiments, use to suffer from so many sports bra issues. However, this role helped her to fully understand each issue, their cause and how to solve them!
I learnt so much testing the performance of sports bras. Including the importance of fit, size and design. I decided to write everything I knew down in a helpful, clear guide to help as many women as possible!
