A slim waterbottle being tucked into a bag.

We all know there’s no excuse not to have a reusable water bottle on hand these days. But, standard cylindrical bottles are so bulky that they often don’t fit well into the typical messenger bag, laptop case, or stylish slim handbag. Enter the Memobottle: an environmentally friendly reusable water bottle in a slim, flat shape that slips easily into any bag.

Like many innovative products, the Memobottle, which is now being sold online here, got its beginnings on Kickstarter. Over 6,000 backers pledged $261,148 AUD to help bring this project to life.

The Australian co-founders, Jesse Leeworthy and Jonathan Byrt, were inspired by their desire to reduce single-use water bottle consumption. (According to the Memobottle site, 50 billion single-use bottles are purchased each year in the United States, and 1,500 of them are discarded every second. Not to mention, bottled water is about 1,400 times more expensive than tap water and often less regulated.) But Leeworthy and Byrt also experienced frustration with standard water bottle designs that didn’t fit into their school bags and laptop cases — places where one would typically store a reusable water bottle.

“Somewhere along the line, society became fixated on designing cylindrical shaped bottles, from this car drink holders and bottle accessories followed suit. Rather than making a product that conforms to the status quo, we decided to flip the equation and create something that is easy to transport but still holds the functional aspects of traditional bottles,” says Leeworthy.

The Memobottle size comparison.

The bottle takes on the dimensions of the A5 and A6 international paper sizes, allowing it to conveniently slide into your bag alongside your laptop, books, and other belongings. At 3 cm wide and 33 mm thick, the A5 Memobottle holds as much liquid as a standard water bottle, 750 ml, but doesn’t take up nearly as much space as its counterparts. The A6 is small enough to hold in your hand while jogging or walking, or to put in your pants or coat pocket, and holds 350 ml. The site identifies this size as suitable for an active or social lifestyle. The bottles are sold at $27 and $24. Gift cards are also available on the site.

The contents of what's inside a bag.

Despite it’s unique shape, some may find fault with the material of the bottle itself — the bottles are made of BPA-free plastic. Many reusable water bottles are made of glass in an effort to combat the mass production of plastic throw-a-way bottles. But according to the product’s site, the Memobottle “holds the ability to become a vehicle that changes society’s mentality around how water can be transported and consumed. It is the balance between improved life convenience and environmental responsibility. It’s a common belief that plastic is the Devil. However, due to the monstrous embodied energy in aluminum and stainless steel products, (considering raw material to product) reusable plastic bottles are actually 80% more environmentally friendly than their counterparts.”

Even though it’s suggested that you hand wash the bottle, they are dishwasher and freezer-safe. They stand upright on their own and are leak-proof. Each bottle comes with both a black and a white lid, a Memobooklet, and recycled cardboard packaging.
