Compare the A5 and A6 memobottle sizes side by side. Learn which flat, stainless steel bottle fits your bag, hydration needs, and daily routine best.
Quick answer
Choose the A6 memobottle if you carry a small handbag or cross-body bag and want a compact daily companion. Pick the A5 memobottle if you need extra capacity for all-day hydration and have space in a backpack or tote. Both share the same paper-inspired, flat design that slides into bags without bulging.
Capacity and size differences at a glance
The A5 memobottle holds more water than the A6, making it the better choice for long workdays, gym sessions, or outdoor trips where refills are scarce. The A6 memobottle is smaller and lighter, ideal for short commutes, errands, or when you want to keep your bag ultra-slim.
Both bottles are made from stainless steel and share the signature flat shape inspired by paper sizes. The trade-off is straightforward: the A5 gives you hydration range but takes up more bag real estate, while the A6 saves space but requires more frequent refills.
Bag compatibility and everyday carry
The A6 memobottle fits easily into handbags, cross-body bags, and small backpacks without adding bulk. Its compact size means you can slip it into a side pocket or next to a wallet. The A5 memobottle is better suited for larger bags like a backpack or the A3 Daily Bag, which includes a dedicated A5 pocket alongside padded laptop storage.
If you often carry a laptop and a bottle together, the A5 pairs naturally with a 16-inch laptop in the A3 Daily Bag. The A6 is more versatile for minimalists who switch between different bag sizes throughout the day.
A5 vs A6: trade-offs to consider
- Hydration range: A5 holds more water, so you can go longer between refills. A6 requires more frequent trips to a water fountain or tap. If you hate refilling, lean toward the A5.
- Bag fit: A6 slips into small handbags and cross-body bags with ease. A5 needs a backpack, tote, or the A3 Daily Bag to fit comfortably. If you switch bags often, the A6 is more flexible.
- Weight when full: A5 is heavier when filled, which may be noticeable in a lightweight bag. A6 stays lighter and is easier to carry one-handed. If you prefer a lighter load, the A6 wins.
