This backpack is designed to fit breast pumps and all the associated pumping gear but it can be used for years beyond pumping! It includes a trolley sleeve on the back for traveling, adjustable straps, a laptop compartment, two extendable side pockets that can be folded back flat for regular use of the interior compartment, and lots of other pockets. The best part is the bag is entirely machine washable! Neoprene for the win. The Earth color is also so unique - it's like a neutral mauve. This bag has one small imperfection on the strap as shown in the picture. It did not affect my use of the bag but Sarah Wells sent me a replacement anyway so that is why I am listing this one. I am open to offers! Send them my way!
