Quick answer

Choosing the right glass water bottle size and caring for the silicone sleeve are simple once you know a few basics. This FAQ covers the most common questions so you can use your bottle with confidence.

Why size matters for your daily routine

The Demi size (650mL / 22oz) is a popular middle ground. It fits most cup holders and bags without being too heavy, making it a good choice for commuting, office days, or shorter outings. If you need a larger volume for long hikes or all-day hydration without refills, consider the larger 32oz size. Smaller 16oz bottles are handy for kids or quick trips.

Sleeve care: cleaning and longevity

The silicone sleeve is removable and easy to clean. Wash it by hand with mild soap and water, or place it on the top rack of the dishwasher. Avoid harsh scrubbers that could damage the silicone. Over time, the sleeve may stretch slightly; if it feels loose, you can replace it with a new one from bkr.

Frequently asked questions

What size glass water bottle should I get?

Consider your daily hydration needs and where you'll carry it. A 22oz (650mL) Demi bottle fits most cup holders and bags, while a 32oz bottle holds more but is larger. A 16oz bottle is compact for short trips or kids.

How do I clean the silicone sleeve?

Remove the sleeve from the bottle. Wash it by hand with mild soap and water, or place it on the top rack of the dishwasher. Avoid abrasive sponges or bleach that can damage the silicone. Regular cleaning prevents buildup and keeps the sleeve looking fresh.

Can I replace the silicone sleeve?

Yes, bkr sells replacement sleeves separately. The Ocean Little Sleeve, for example, is a protective, removable, and interchangeable silicone sleeve that fits Little bottles (500mL/16oz). You can swap sleeves to change the look or replace a worn one. Keep an eye on the sleeve's fit; if it becomes too loose, a new sleeve is an easy fix.

Is the glass bottle dishwasher safe?

The glass bottle is dishwasher safe on the top rack. However, to preserve the sleeve's color and fit, hand washing is recommended for the sleeve. Always remove the sleeve before putting the bottle in the dishwasher.

How do I prevent the bottle from breaking?

The silicone sleeve provides a protective layer against minor drops and bumps. Avoid extreme temperature changes (e.g., pouring hot liquid into a cold bottle). Store the bottle upright when not in use to reduce the risk of tipping over. The sleeve is your first line of defense, but handle the bottle with care as you would any glass item.
