The best reusable water bottle for everyday carry

Related questions

What size reusable water bottle should I buy?

Between 600ml and 750ml suits most people: enough for a working morning without becoming heavy enough to leave at home. Litre-plus bottles make sense for gym, hiking and site work, where refills are inconvenient.

Is stainless or glass better for water?

Stainless is better for carrying, insulation and durability; glass is better for taste, because it holds no flavour or odour at all. Glass is the right choice if the bottle mostly lives on a desk.

How do I get the smell out of a water bottle?

Soak overnight with warm water and a tablespoon of bicarbonate of soda, scrub the lid gasket separately with a brush, and let both dry fully upside down. Persistent smell almost always lives in the lid, not the body.
