Neoprene, invented by DuPont scientists in the 1930s, has hundreds of uses, from Halloween masks to hydroponic gardening. It's best known for use in wetsuits and other swimwear, but it has made surprise appearances in fashion collections by Balenciaga, Lanvin, and Vera Wang. And since neoprene is stretchy, sturdy, and insulates well, it's the perfect material for a stroller organizer that adapts nicely to your needs on the go. The Skip Hop Neoprene Stroller Organizer keeps your drinks cool and keeps your keys, phone, and other essentials right at your fingertips, and fits virtually any stroller, whether it has a single bar or two handles. What more could you ask for? The flexible neoprene body of the Skip Hop Stroller Organizer lets you fit drink cups and bottles of all sizes, and the adjustable Velcro straps let you customize the fit for any stroller (perfect if you've got two or more strollers!). A detachable zip-off wristlet lets you take a few essentials on separate errands, and features a headphone port for hands-free phone calls as you stroll.
