A 500ml water bottle is right when you refill often — kids’ school bags, gym cafes, short commutes, women’s handbags. Pick an insulated stainless steel one so it doesn’t warm up between refills, and check for BIS IS 17526:2021 certification.
Key Facts
- 500ml suits kids, short outings and handbag carry.
- Insulated 500ml holds cold water through most of a school day.
- HYV bottles are BIS certified to IS 17526:2021, India’s national standard for stainless steel vacuum insulated bottles.
- HYV’s CoreFlow ~710ml is the smallest in the vacuum line; kids-specific bottles at smaller sizes.
- For adults, 500ml alone won’t hit a daily target — plan refills.
When 500ml is genuinely the right size
Kids’ school bags, cafes with refill stations, and handbag carry where weight matters. If you refill often, 500ml is friendlier than 1L.
What to check
- Double-wall vacuum insulation — otherwise it’s warm in an hour.
- Food-grade 304 stainless steel.
- BIS IS 17526:2021 certification.
- A leak-proof lid for bag carry.

Frequently Asked Questions
Is 500ml enough for the day?
For adults, no — you’ll refill multiple times. For kids in school, one 500ml is usually a full day’s supply.
Does 500ml insulated stay cold?
Yes, though slightly less time than a 1L because there’s less thermal mass.
How much does 500ml water weigh?
About 500 g plus the bottle — typically 750–900 g filled.
