Stainless steel without the weight
The main objection to steel bottles is weight. Super Sparrow answers with flow forming, a process that thins the wall: the brand quotes 26% less weight with no loss of strength.
Mirror-polished 18/10 steel
The inside is electropolished: a smooth surface that cleans easily and does not hold odours. The bottle is free of BPA, BPS and phthalates.
For packs where every gram counts
Hiking, cycling, trail running or school: this is the insulated bottle to pick when lightness comes first.

Frequently asked questions
What is the difference between 18/8 and 18/10 steel?
18/10 contains a little more nickel, which improves corrosion resistance.
Which sizes are available?
The brand lists 350, 500 and 750 ml; availability varies by country and colour.
Is the price the same for every size?
No: it depends on the size and colour, and Amazon regularly runs limited-time deals. Every button on this page opens the exact version with today’s price.
