Popular Model: One KAI Air Carry Positions: Vertical, Back Carry, Forward-Facing Purchased new in 2020 and used for about a year for two children. Both children started daycare at age 0, so the usage period was short. Used only on weekends for outings, as a secondary carrier. Another carrier was used at home, so the frequency of use was low, and there are no pills or stains. As shown in the photos, there is no fading or feeling of use. Cleaned with oxygen bleach.
