Fantastic little cooler bag form 'So Young' for anybody - not just for kids! It's perfect as a bottle bag for baby, as it can be snapped onto the stroller or pram handlebars, but it is also cleverly adaptable with strapping (included) to wear over the shoulder(messenger style) or as a backpack. This little cooler bag is made from linen which has been coated to make it easy to wipe clean. I also has a sparate removeable layer which can be easily washed, dried and replaced. PVC, Phthalate and Lead free.
