BabyBjorn Baby Carrier ONE KAI Air Anthracite I believe I have the instruction manual, but I'm still checking. This baby carrier features breathable mesh material and adjustable straps. - Material: Mesh - Features: Adjustable straps - Safety Feature: Buckle closure There are no noticeable flaws. Please forgive any minor imperfections due to it being a used item. I've always used Bjorn baby carriers. The straps are easy to adjust, making it easy for both parents to share. It's a gender-neutral color, somewhere between gray and black, and my husband used it often. Those considering Ergobaby, etc., please consider this as well.
