The best way to render field content without any  wrapper
Look in the core modules/field/theme/ folder, copy the field.tpl.php file to your theme then rename it to whatever the system name for the field is. i.e field--body.tpl.php

Edit the file to remove the surrounding divs and anything else you don't want. All you actually need is the foreach and the render($item);

Don't forget to clear the cache so it will pick up the new file, hope that helps.
