Mei Tai Carriers
Half Buckle and Velcro waist carriers
Hybrid carriers with buckle or Velcro fastenings rather than being tied at waist. This can help if you are nervous about undoing the wrong knot.
podaegi and Onbuhimo Carriers
Pods and Onbuhimo are traditional Asian Based Carriers (Korea and Japan). They do not have waistbands but fastened by means of long straps or rings.
