Override Woocommerce Font-size css

Hello. I am running the Customizr Theme and have the latest version of Woocommerce as a plugin. I don’t want to change a lot, but the product titles on this page are too small: http://newportlobstershack.com/shop/ ‘Inspecting the element’ shows that “font-size: 1em;” is the problem. That code comes from the woocommerce.css rather than the theme’s. Disabling that makes it all look fine. But I don’t know how to do overwrite this piece of code in the site. Customizr has a custom css space, but what I have tried hasn’t worked at all. I have gone through the woocommerce.css file, just to see if I could find the magic “font-size: 1em;” to change, but I cannot figure out which one it is.

I created a child theme but haven’t put it into use yet as this is the only thing I want to change and wonder if it can be done by custom css. Not very experienced and don’t know how to use hooks. I have read though several posts/forums before starting this thread. Perhaps the fix is simple but I cannot figure it out. Thanks for any help.
