Cathy and Wayne take a light hearted look at the science of layering: why we sweat, why "wicking" is important, how layers keep us cool AND warm, why more and more clothes are being made from plastic bottles and tree fibres, nasty chafing and why, when it comes to technical underwear, going large is good. In fact there is a lot of talk about underwear. Men's and Women's. It is also highly likely that this is the first ever Podcast to coin the term "Hurty Boob Day"!
