I have a 99% new Ergobaby carrier. It supports front inward, front outward, back, and hip, four ways of carrying your baby from 12-45lbs. It comes with mesh material to maximize air flow to prevent baby from over heating when use during summer. It also has a tucked in cover for sun protection and breast feeding. Adjustable seat and shoulder height to accommodate sizes of baby and parents. The wide waist band is used for lumbar and waist support so that it's not relying on parents' back too much. It is pretty much the best carrier on the market. It's only used a couple of times since we bought it from store. It was intended mostly for traveling, but due to covid, it wasn't used as much as we would have planned. So it's in PERFECT condition, no stain no scratches, from pet free smoke free home. Manual and box included. Retail price 240$.
