I think it is universally true that women are uncomfortable pumping in front
of men. Most women don't like to pump in a crowd -- of either gender. But I
don't think the issue is so much the equipment as much as the relative
nudity. When you breastfeed, little or nothing typically shows. There is
much more exposure involved in pumping. I think the general unwillingness to
be half-naked is the biggest driving force.
