Water Bottle

Drinking enough water is simple in theory and easy to forget on a busy day. This 500 ml stainless steel water bottle is made to sit within reach and stay there: on a desk beside a laptop, in a bag, in a bicycle holder, on the edge of a gym mat.

The wall is double, so the temperature holds. Cold water is still cold at the end of a morning and tea stays hot through a long meeting. Because the insulation is in the wall, the outside stays dry: no condensation ring on a desk, no damp patch in a bag. Stainless steel also keeps water tasting like water, whatever the bottle held the day before, which is the usual complaint with plastic.

The screw lid seals properly and contains no BPA. Empty, the bottle weighs around 250 grams, light enough to carry all day and solid enough to survive being knocked off a table. It takes the standard size of bicycle bottle holder.

Three matte colours are available: soft yellow, white and black.

Care is straightforward. Wash the bottle by hand in warm water with a mild soap and leave it open to dry, which keeps the inside fresh. The lid is not suitable for the dishwasher, because the seal and the thread last longer without it.

The bottle is an accessory rather than a supplement, and carries no health claims. It exists because a reusable insulated bottle is the least complicated way to drink more water in a day, and because it replaces a great many single-use ones.
