Kaally Glass Bottle 500mL

This glass water bottle with straw was designed around one simple principle: every surface that touches your mouth should be silicone. The borosilicate glass body is taste-neutral and temperature-resistant, so your drink tastes like nothing but itself — no plastic aftertaste, ever. A protective silicone sleeve wraps the glass body — it absorbs everyday knocks and drops, and gives each bottle its soft colour. The straw, outer sipper, and inner seal are all independently LFGB-certified silicone, and the only plastic anywhere in the bottle is the internal lid structure: food-grade, BPA-free PP that never touches your lips.

Why Families Choose This Glass Water Bottle with Straw

Most “glass” drink bottles still rely on plastic for the parts that actually touch your mouth — the straw, the spout, the seal. This one doesn’t. Every mouth-contact surface is LFGB-certified silicone, the same standard used for baby bottle teats, so switching to glass doesn’t mean trading one set of unknowns for another. The 100% leakproof flip-top lid keeps the straw clean between sips and means this bottle can go straight into a bag without a backup liner, and the wide neck makes it easy to fill, add ice, and clean by hand.
If your family needs more on hand, the 800mL Kaally Glass Bottle uses the same materials and design in a larger size — handy for school-aged kids, gym bags, or keeping one bottle style across the whole household. Want a spare lid for the car, or a second straw to swap between kids? The Kaally Bottle Silicone Lid & Straw Set and Kaally Bottle Sports Lid both fit this bottle, and a Silicone Straw Cleaning Brush keeps the straw spotless between washes.
Whether it’s heading to school in a lunchbox, sitting on a desk at work, or living on a bedside table overnight, this glass water bottle with straw is built to be used daily without thinking twice about what’s touching your drink. It’s a popular pick for new parents setting up a low-tox kitchen, gift-givers after something that won’t end up in landfill within a year, and anyone simply switching away from single-use plastic bottles for good.
