If you go to lanacane.com. they are offering a free sample of Lanacane Anti-Chafing Gel. I am thinking that this could be handy for sensitive tummies that rub on clothes, not to mention other parts of the body the can get hot and chafe in the summer. :-)
Here's the product description from their products page:
Lanacaneā¢ Anti-Chafing Gel soothes and prevents chafing caused by friction such as repeated rubbing of skin on skin or skin on clothing. It helps skin heal by reducing further damage from chafing.
