  • Names the inner coating as polyamide rather than leaving the inside of a metal bottle undescribed
  • Stated to take water, juice, isotonic and carbonated drinks, and stated taste-neutral with it
  • The narrow neck is the selling point and is never given a diameter, so nothing can be known about what screws on

Best for: A day out where a metal bottle on a strap suits better than plastic, and nothing else has to attach to it.

What this listing puts on record

A 1.5 litre aluminium bottle with a screw closure and a narrow neck, an inner coating of polyamide, and a statement that it is free of bisphenol, phthalates, lead and other harmful substances. It is stated taste-neutral and suitable for water, juice, isotonic and carbonated drinks. Hand washing is recommended because of the narrow neck, and hot drinks are ruled out by the maker. The bottle is stated airtight, reusable and fully recyclable, with a cover available separately.

The neck decides, and it is only ever an adjective

Narrow, twice, without a millimetre. Mouth diameter is the specification that says what else can be screwed on — a filter, a straw lid, a replacement cap — and it is the one this listing never gives. Only two of the seven bottles in this hub publish a figure; this is among the five that do not.

The consequence is practical rather than theoretical: a narrow neck is also the reason the maker gives for hand washing, so the same unmeasured dimension governs both what fits and how it gets cleaned.

What the metal is, and what it is not

Aluminium with a polyamide inner coating. Naming the lining matters on a metal bottle, because the lining is what the drink actually touches, and most listings on this shelf skip it.

There is no insulation claim of any kind, and none should be read into the metal: the maker rules out hot drinks explicitly. Bottles built to hold temperature are kept in a separate family on this site.

The drinks it names

Water, juice, isotonic drinks and carbonated ones, with the bottle stated airtight. Carbonation is worth noting, since a cap that holds pressure is a different part from one that merely holds liquid.

Before ordering

If anything has to screw onto this bottle, ask the maker for the neck diameter first. If nothing does, the litres, the coating and the loop are the three things the listing publishes, and all three are useful.

Availability

Selling at about 9 € on the German and Spanish Amazon stores when this page was checked.

It also sells on the American and British Amazon stores in the local currency, which the range above does not cover — that range counts euro stores and nothing else.

The French and Italian Amazon price sits more than 1.6× above the cheapest store. That gap usually means a reshipper rather than a local seller, so those listings are kept out of the range above.

    • One of only two bottles in this hub that publishes a mouth diameter, and it gives it in millimetres at 35 mm
    • Publishes a body diameter of 75 mm and a height of 280 mm as well, which is what decides whether it drops into a bottle cage
    • The 35 mm figure is the opening, not a thread standard, so it still does not say what would screw on

    Best for: A bike cage or a narrow rucksack pocket, where the 75 mm body matters as much as the litre inside it.
