Neither too big nor too small, the "Middle" will allow you to carry all your essentials for a day with baby! It can be positioned on the stroller thanks to its adjustable shoulder strap or stroller attachments, and it will accompany you on all your outings. The interior of the bag, completely waterproof, consists of 2 flat pockets and 2 bottle pockets, and on the outside, 3 additional pockets (2 elastic pockets on the sides and 1 pocket at the front). The stroller attachments are sold separately.
