The entire cost of the Totes goes to the project, to build fresh water wells in Haiti.
You can follow the link above for more information about the Totes specifically, or read more about how the project got started with this press-release.
"I want to bring water to a dry, dusty place to bring life to its people who are struggling daily to eat, to bathe, to live with human dignity. I want to build a well in Haiti to help the people grow food to feed themselves and their families. I can’t build a well myself -- but there are people who can at Food For The Poor.
Instead, I can sew, and I am making tote bags to sell to help Food For The Poor raise the money necessary to build a well for a village in Haiti."
They also make handy baby totes (of course, I'm kidding, but who doesn't love a baby in a bag??):
