I purchased this in preparation for the birth of my first child in the summer of 2023 and used it until the baby was about 2-3 months old. I also used it a little for my second child, born in the fall of 2025, from the time we left the hospital until they were about 1 month old, but they didn't like baby carriers, so I hardly used it. It's made of mesh material, but since I dress my baby in thick clothes in the winter and also put an outer layer on, I never felt that the mesh carrier was cold. I've also used a carrier I received as a hand-me-down that didn't have size adjustments, but this one does, so my husband, grandparents, and I could all use it. It was convenient because I could adjust it whether the baby was lightly dressed or wearing a sweater. I especially found it useful during the newborn period because the baby slept soundly in it more than in other carriers. Home-cleaned. It's in good condition with no noticeable damage, but it is a used item, so please purchase only if you understand this. The color is brown. In addition to the main body, a support belt and storage bag are included (see photos 2 and 3). Please read my profile to avoid any problems.
