Best Breast Pump Bags

Like many of the best baby products on the market, this bag was created by a mom who couldn't find a breast pump bag she wanted on her daily commute to and from work — hence the eponymous Sarah Wells line of bags was born. The Lizzy is named after her younger sister and fits the Medela Pump in Style, Medela Freestyle, Spectra S1 and S2 and more. With a handy side zip pocket, Spectra users can use the pump without even taking it out of the bag. It has thermally-lined pockets that can store pumped milk in bags or bottles for up to six hours with ice packs (not included). Another thoughtful element is two photo pouches to store your babe's photos to help with let-down. There's even room for a 15-inch laptop. It comes in many fun prints and colors.

One of the newer offerings from Petunia Pickle Bottom is also one of its most versatile. The soft, suede-like faux leather exterior means your partner won't mind carrying this bag for you when you're on the go. It has an extra-wide opening and a large main compartment to hold the PPB Prompt Pump Kit made for Medela pumps. The insulated front pocket can hold two large bottles or milk bags and it has a separate padded interior sleeve that's large enough to fit a 17-inch laptop.

With fewer parts to a Willow pump, you can get away with using a smaller pump bag — like this GoGoSo bag with a built-in cooler. The bottom half of the bag unzips to reveal space for up to six breast milk bags or three breast milk bottles and freezer packs. Another hidden extra that makes this bag a top pick is its USB charging port. The bag looks like a vintage handlebar your granny might have carried, or you can wear it as a backpack. The polyester bag can be hand washed but can't go in the washing machine.
