This is an adjustable baby carrier made with breathable mesh material. - Colors: Black and Gray - Materials: Mesh and Nylon - Adjustable Straps: Yes - Back Style: Mesh back - Design: Simple and compact I used this quite a bit for raising twins! It's not in perfect condition, but it holds a lot of memories, so I'd like to pass it on to someone who needs it. Please consider this item only if you understand that it is a used item, as I may have missed some things during my amateur inspection!!
