Why It Made The List
Flat, A6-sized, and finished in sleek, satin-textured powdercoat, this stainless steel flask feels tougher and more refined than its transparent Memobottle cousins. Built to handle life's knocks and bumps, it slips easily into bags, backpacks, or jacket pockets, its slim shape tucking neatly between books, laptops and devices. With 500ml capacity it's practical for daily hydration, but its compact form works perfectly as a hip or spirit flask when the occasion calls. Hardy, discreet, and undeniably cool, it’s a piece of kit that looks sharp, keeps you lubricated and holds its own wherever you take it.

The A6 Stainless Steel Memobottle holds 500 ml and measures 181 × 105 × 37 mm, shaped to mirror the dimensions of an A6 notebook.
Its novel, slim profile slides effortlessly into shoulder bags, seat pockets, backpacks or jacket pockets, fitting comfortably where round bottles simply won’t fit.
Its body is constructed from premium food-grade 304 stainless steel, finished with a satin-textured powder coat that balances elegance with scratch resistance.
The stainless surface is robust and stain-resistant, offering durability and a distinctly refined aesthetic.
The bottle neck features an innovative internalised thread and fast-flow mouthpiece, with a wide 28 mm opening that simplifies filling and improves drinking.
The design keeps the drinking surface covered when not in use, contributing to clean, unimpaired hydration.
Sealed by a lid made of BPA- and BPS-free plastic and food-grade silicone, the bottle is reliably leak-proof. It’s also safe to use with both hot and cold beverages—even freezer storage and boiling water are supported, making it as good for spirits as it is for coffee.
At 320 g, its solid but unfussy weight matches the stainless build, giving it a substantial, dependable feel in hand.
Cleaning is straightforward—warm water and soap do the job, and for particularly deeper cleaning, Memobottle’s cleaning tablets can be purchased separately.
Each bottle comes with a two-year warranty, and as with all Memobottle products, purchase helps support safe water access through their partnership with Water.org.
