【Size Adjustment Function for Both Men and Women】The simple design allows for easy size adjustment by simply pulling the waist belt. It can be worn by people of all genders, body types, and ages. 【Reduces Strain on Shoulders and Waist】Conventional baby carriers often put stress on specific areas of the waist and shoulders. This stress can cause chronic stiffness and pain, making it difficult to wear them for long periods. To solve these problems, this product is designed to distribute weight over a wide area of the shoulders and the waist, making it less likely to cause strain. 【Compact Design for Easy Carrying】The belt part serves as a storage pocket, allowing you to fold it up and flip it over for compact storage. It's a lightweight design that won't take up much space in your bag when you're out and about.
