Kaally Glass Bottle 800mL

This large glass water bottle with straw holds 800mL and follows the same design principle as our smaller Kaally Bottle: every surface that touches your mouth is silicone, never plastic. The borosilicate glass body keeps every drink taste-neutral — no plastic aftertaste, even after months of daily use — and the silicone straw, outer sipper, and inner seal are all independently LFGB-certified. The only plastic anywhere in the bottle is the internal lid structure: food-grade, BPA-free PP that never reaches your lips. A protective silicone sleeve wraps the glass body — it absorbs everyday knocks and drops, and gives each bottle its colour.

Why Families Choose This Large Glass Water Bottle with Straw

800mL is enough for a school day, a long commute, or a gym session without a refill — and because the straw, sipper, and seal are silicone rather than plastic, a bigger bottle doesn’t mean a bigger dose of plastic touching your mouth. The 100% leakproof flip-top lid keeps the straw covered and clean between sips, and the wide neck makes it easy to fill, add ice, and hand wash.
If 800mL is more than you need day-to-day, the 500mL Kaally Glass Bottle uses the same materials and design in a smaller size — good for younger kids or smaller bags. Want a spare lid for the car, or an extra straw to swap between bottles? 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.
This large glass water bottle with straw is a popular choice for school lunchboxes, work desks, and gym bags — anywhere a bigger bottle means fewer refills during the day. Like the rest of the Kaally range, it’s designed for families building a low-tox kitchen one swap at a time, without needing to replace it again as kids grow into bigger appetites and longer days away from home.

Large glass water bottle with straw — common questions

Is the 800mL bottle leakproof?

Yes — the flip-top lid seals 100% leakproof when closed, so it travels in a bag without a backup liner.

Does this glass bottle have a silicone sleeve?

Yes. A protective silicone sleeve wraps the borosilicate glass body — it absorbs everyday knocks and drops and gives each bottle its colour.

Is it dishwasher safe, and how do I clean the straw?

Every part is top-rack dishwasher safe and the bottle fully comes apart. See our guide to cleaning silicone straws to keep the straw fresh.

Is 800mL too big? Who is it best for?

800mL suits older kids and adults who want fewer refills — school days, work, gym and long outings. If you’d prefer a smaller size, the 500mL Kaally Glass Bottle uses the same design. For toddlers and babies, choose the KaaKaaBaby glass bottle with straw and silicone sleeve.
