The Beco Butterfly 2 has long been a favorite carrier of ours for so many reasons. First and foremost, however, is the ease with which we can fit the carrier to most any body type. So many soft structured carriers are designed in such a way that only some people can get a really good fit, and when it comes to baby carriers, fit is everything! The adjustability of the Beco Butterfly is outstanding. It has multiple adjustments that give the carrier flexibility and provide comfort to everyone who wears it.
