The A7 memobottle holds 180ml and slips into a clutch, blazer, or pocket. Here is what actually fits inside, plus honest limits and when to size up to the A5.
Quick answer
The A7 memobottle holds 180ml, making it the most compact bottle in the memobottle collection. Buy it if you want a flat bottle that fits in a clutch, blazer, or pocket and you refill often; choose the A5 memobottle instead if you want one fill to cover a full day.
What 180ml Actually Gets You
A 180ml fill is roughly a large espresso cup, a small juice glass, or about six to eight normal sips. That is enough for a short errand, a meeting, a flight takeoff, or the walk between train and office. It is not enough to replace a full-size bottle across a workday, so treat the A7 as a top-up bottle you refill rather than a single-fill hydration plan.
This is where the A7 memobottle capacity question usually gets answered honestly: the bottle is not designed to carry more, it is designed to carry less in a shape that goes where round bottles cannot. If your day involves long stretches without a refill point, the capacity will feel tight by early afternoon.
Where the A7 Fits and Where It Does Not
The A7 is built for flat, narrow spaces: a clutch, a blazer inside pocket, or a trouser or coat pocket. Its paper-inspired flat form is what makes those placements possible, and it is the same design logic that lets the larger A5 memobottle slide flat against books and a laptop in a bag.
Where it does not fit: a standard round bottle holder, a bike cage, or a car cup holder sized for cylindrical bottles. Those holders grip by circumference, and a flat bottle has none to grip. If a cup holder or cage is non-negotiable for you, this shape is the wrong tool regardless of size.
A7 vs A5: The Size Decision
The A7 is the most compact bottle in the collection at 180ml; the A5 memobottle is built for effortless all-day hydration with an extra large capacity and a space-saving form that fits flat in a bag. That is the real trade: the A7 wins on pocketability, the A5 wins on refill frequency.
A practical test before you buy: count how many times per day you would honestly refill a 180ml bottle. If the answer is more than three or four, the A5 will suit you better. If you mostly need a sip between short trips and you carry a bag anyway, the A7 is the one that actually leaves the house with you.
Decision rules for buying the A7
- Rule 1: Pocket or clutch is the priority: If the bottle must disappear into a clutch, blazer, or pocket, the A7 is the only memobottle sized for that job. Buy the A7.
- Rule 2: One fill must last the day: If you do not want to refill more than once or twice a day, 180ml will not cover it. Step up to the A5 memobottle.
- Rule 3: You need a cup holder or bike cage: Flat bottles do not sit in round holders, regardless of capacity. This shape is not for you; keep a round bottle for those moments.
- Rule 4: You already own a Stainless Steel memobottle: Replacement lids are model-specific; the Copper Lid is compatible only with the Stainless Steel range. Match the lid to your bottle range before ordering.
Product facts
- A7 memobottle: The A7 memobottle is the most compact in the memobottle collection and holds 180ml. This is the smallest memobottle size, so it is the model to pick when pocket or clutch fit matters more than capacity.
- A5 memobottle: The A5 memobottle is built for all-day hydration with an extra large capacity and a space-saving form that fits flat against books and a laptop. Choose the A5 when one fill needs to last a workday and a flat bag fit is enough.
- Copper Lid (Stainless Steel memobottle): The Copper Lid is a spare or replacement lid with a silicone seal for a leak-proof fit, compatible only with the Stainless Steel memobottle range. If you own a Stainless Steel memobottle, this is the correct replacement lid; it will not fit the A7 or A5.
- Mandarin Desk Stand (Original memobottle): The Mandarin Desk Stand is made from powder-coated steel and is compatible with the Original memobottle collection and Silicone Sleeve range. A desk stand keeps a flat bottle upright at home, but check compatibility before buying if your bottle is not an Original model.
