I purchased this last year, but I'm selling it because I haven't had a chance to use it. It's new and unused, and a great deal as it's cheaper than the retail price. The ergonomic OMNI 360 is suitable for babies from 3.2 to 20kg and features cool air mesh for comfortable carrying. - Brand: ergobaby - Model Name: OMNI 360 - Weight Limit: 3.2～20kg - Waist Size: 60～132cm - Features: Ergonomic design, cool air mesh Thank you for looking.
