Tech pod, ep. 14: How to layer for winter riding

Don't be such a Dan! A Dan?! That's right, our tech podcast host Dan Cavallari is a bit timid about riding in foul weather. Not to worry because today he is talking with Rob Pickels, physiologist in advanced development at Pearl Izumi. They discuss how breathability works (and why that is a misnomer), how waterproof your cycling kit really needs to be, and why zippers actually don't work that well if you need to cool off. Pickels has plenty of insight on how different fabrics work in different conditions and advice to help you layer more effectively this winter.
