At iDiaper.com, one of our reusable products is reusable unisex briefs. These reusable unisex briefs are the most ecologically friendly products that we have. Since you are not throwing away five to ten diapers a day, that's a lot of room in a landfill over the course of a year. If just a few people switch to reusables over the course of several years, you could be talking about a football field of reusable briefs that didn't have to be disposed of at all. Instead, they are machine washed and produce no waste at all. Use an energy conscious, ecologically safe washing detergent to wash these in and you've even been more healthy for the earth.
