The Flat Water Bottle That Fits Your Life (and Your Bag)
I recently packed two memobottles for a trip to Belize. One A5 (medium) with a silicone sleeve, one A6 (large) without. Both slid flat into a suitcase without taking up any real space, and the smaller one rode inside a backpack where the kids could reach it.
My kids are always thirsty but never seem to have their water bottles. The flat shape made it low-risk to toss them in, and five years after I bought them, I'm still carrying both.
That kind of durability, paired with a design that actually fits into the way people move through their days, is exactly what drew us to memobottle in the first place.
WATCH Brittney quickly show you the memobottle:
Memobottle was born from a similar impulse. Co-founders Jesse Leeworthy, a product design engineer, and Jonathan Byrt, a financial consultant, grew up in a small coastal town south of Melbourne, Australia, where they watched single-use plastic bottles wash up on beaches and choke waterways. They understood something that felt almost too simple: if a reusable bottle were actually convenient to carry, more people would carry one.
So they asked a question that changed everything.
What if a water bottle were shaped like the things already in your bag?
Why Flat Reusable Water Bottles Make More Sense
The paper-sized design is the first thing people notice about a memobottle, and it is also the reason the bottles work so well in daily life. Sized to match international paper standards (A5, A6, and A7), each bottle slides flat against a laptop, a stack of books, or a planner inside a bag. No more bulging side pockets. No more bottles that tip over the second you set them down on a desk.
But the shape is not just a design novelty. Flat bottles take up less space, which means they are more likely to come along for the commute, the meeting, the airport, the errand run. And the more often a reusable bottle travels with you, the fewer disposable bottles end up in landfills and oceans.
Memobottle estimates that their products have helped prevent the consumption and waste of over 200 million disposable bottles worldwide.
That kind of impact starts with convenience. A bottle you actually want to carry is a bottle that replaces dozens, even hundreds, of single-use alternatives over its lifetime.
What Makes Memobottle Different from Other Reusable Bottles
Beyond the flat, space-saving shape, memobottle stands apart in a few meaningful ways.
Every bottle in the collection is BPA and BPS free. The Tritan plastic options offer glass-like clarity in a lightweight, shatterproof material that handles both hot water and freezer temperatures. The stainless steel versions feature a satin powdercoat finish, a fast-flow mouthpiece designed for easy filling and quick hydration, and a leak-proof lid with a durable silicone seal. All memobottles come with a premium stainless steel lid.
Memobottle is also a certified B Corporation, joining a global community of businesses committed to using commerce as a force for good. And as a proud supporter of Water.org, every memobottle sold provides one person in need with five months of access to safe water. To date, the company has helped provide over 50 million days of safe water for communities around the world.
That is the kind of story behind a product that makes carrying it feel like more than just staying hydrated.

Choosing the Right Memobottle
The right size depends on how and where you plan to carry it. The A5 is the workhorse for long days at the office, travel, or anyone who refills less often. The A6 is ideal for lighter carry, quick outings, or as a second bottle for a child's backpack. The Slim works beautifully for people who prefer a traditional tall-bottle feel with the added benefit of a narrower profile.
For material, the Tritan plastic bottles are the lightest option and offer the visual satisfaction of watching your water level throughout the day. The stainless steel versions are more durable, handle boiling water, and have a premium weight and finish that feel substantial in the hand.
And these bottles last. Brittney's have been in regular use for five years, which is exactly the kind of longevity that makes a reusable product worth owning. Every memobottle in the collection meets the same standard: thoughtfully designed, built to last, and made by a company that measures success by more than just sales.
Plenty Mercantile stocks memobottle because the brand reflects the same values that guide every product on the shelves: buy fewer things, buy better things, and let those things serve you and the world well.
