The mesh can be covered with a special fabric of the same design, which lets you to use the carrier all year round. You can adjust panel width with a velcro fastening and fit the carrier to 3-4 months old babies, as well as to older 3-year-old children wearing up to 110 size (or weighing from 3.5kg up to 20kg).

It’s the perfect carrier for the whole babywearing period. All Kinder Hop baby carriers are recommended by the International Hip Dysplasia Institute as safe and healthy for the hip joints.
