Slim, tall glass bottles built for smoothies and thick shakes as much as everyday water — the wide mouth means you can actually get a spoon or ice cubes in, and fruit chunks won't get stuck the way they do in a narrow-neck bottle. Tempered borosilicate glass handles hot and cold drinks equally well, from morning tea to iced coffee.

The stainless steel cap seals airtight, so it's genuinely leakproof in a bag rather than just splash-resistant. Glass won't hold onto odors or stain the way plastic can over time, so your infused water tastes like what you put in it, not last week's smoothie. The tall, narrow shape slides easily into a car cup holder or a crowded fridge shelf.

Set of 4 bottles, 16 oz / 500ml each, measuring 7.8in tall and 2.6in wide. Made from borosilicate glass with a stainless steel cap and clear plastic lid. Dishwasher safe for the bottles; hand-wash the lids only. For anything besides water, fill to 80% capacity since carbonated or fermenting drinks can build pressure. Not recommended for the freezer, but fine in the fridge.
