For quick off and on and wonderful support for babies from about birth up to 3-4 years old - buckle carriers are the favorite of many families. Buckle carriers have many options for colors and designs, from solid neutral colors to beautiful fabrics and wrap conversions (a buckle carrier made partially or completely from woven wrap fabric). These carriers can be worn for front and back carries. Buckle carriers have a back panel where the baby sits, like in a mei tai, but have a waist strap with a buckle and the shoulder straps are backpack style. Most buckle carriers have a wide range of adjustment for different height and size of adults.
