The narrowest side-by-side twin buggy on the market. Only 25” wide! Mountain Buggy, like phil&teds, is known for the ease and glide of its push. This stroller is no exception...it turns on a dime, and though a double, it has the same footprint as a single stroller. If you want a side-by-side, you can't get any more sleek and trim than the Duet.
