Usable from 10 days old to 3 years old. Made of mesh material for good breathability! 3-way use: Horizontal carry, vertical carry, and back carry. - Color: Navy - Features: Mesh material - Adjustable straps: Yes - Accessories: Instruction manual Purchase date: April 29, 2025 I bought this looking for something usable for newborns. I used it about 3 times. There are no stains. After that, I bought an Ergo and switched to that. I found the strap adjustments a little difficult depending on the carrying style. I recommend watching YouTube videos to help with the adjustments. I will ship it without the box. Thank you.
