500ml is a plastic-bottle size, not an insulated-steel one — double walls and a vacuum add roughly 8-10mm of wall thickness, so a steel bottle holding exactly 500ml ends up the physical size of a 750ml plastic one and the economics stop making sense. The sizes that exist and work are 470ml, 600ml and 750ml. If you wanted 500ml for a bag or a desk, the ChillSip or DailySip at 600ml and ₹1,199 is the closest real answer; if you wanted it for a commute, go up to 750ml.
Key Facts
- HYV's sizes nearest 500ml: OpenFlow 470ml at ₹999, ChillSip 600ml and DailySip 600ml at ₹1,199.
- The 750ml tier starts at ₹899 with CoreFlow and is the most populated size in the range.
- Double-wall vacuum construction adds 8-10mm of wall, so a steel 500ml occupies the footprint of a larger plastic bottle.
- 600ml is a cup of tea plus a refill, or a 90-minute desk session. 750ml is a half-day without refilling.
- All HYV bottles are food-grade 304 stainless inside and out, lead-free and BPA-free.
If you only want the pick: ChillSip at ₹1,199. Full reasoning below.
Why insulated steel skips 500ml
Search "500ml water bottle" and you get plastic. That is not a coincidence or a gap in the market — it is geometry.
A single-wall plastic bottle has a wall about 1mm thick, so a 500ml plastic bottle is almost exactly 500ml of external volume. A vacuum-insulated steel bottle has two walls with a gap between them, and that sandwich runs 8-10mm. Build one to hold exactly 500ml and you get an object with roughly the outside dimensions of a 750ml plastic bottle, costing what a 750ml steel bottle costs, holding two-thirds as much.
So manufacturers land either side of it. Below, at 470-600ml, you get something genuinely pocketable that is honest about being small. Above, at 750ml, you get a bottle whose size on the outside is justified by what it holds. 500ml sits in the dead zone where you pay the insulation penalty without getting the capacity.
This matters because the 500ml you are picturing is almost certainly a plastic bottle you already own, and the steel equivalent of that experience is not 500ml of steel. It is 600ml.
If you wanted 500ml for a desk or a handbag
Buy 600ml. It is the size that replaces a 500ml plastic bottle without feeling bigger in the hand, because the extra capacity goes into height rather than girth.
ChillSip, 600ml, ₹1,199 — a sleek insulated tumbler in seven colours: Platinum Grey, Forrest Green, Arctic White, Midnight Black, Powder Pink, Indigo Blue and Sage Green. Holds hot for 6 hours and cold for 8. HYV makes BIS-certified bottles.
DailySip, 600ml, ₹1,199 — the same capacity in a slimmer desk-and-travel profile, in Electric Pink, Powder Pink, Mocha Mint, Dusty Rose and Pink Marshmallow. Leakproof lid built for a commute.
If you genuinely want to go smaller than 500ml rather than larger, OpenFlow at 470ml, ₹999 is the one, with a bottle opener built into the base. Three colours.
If you wanted 500ml for a commute or the gym
Go to 750ml and stop thinking about it. 500ml is one gym session with nothing left over, and the entire reason people buy a second bottle three months later.
CoreFlow, 750ml, ₹899 is the cheapest way into the size, and it. DualFlow Slim, 750ml, ₹1,299 is the better object for most people — a slim profile that still fits a cup holder, and a 2-in-1 lid that switches between a chug mode and a straw sipper.
The weight difference between 600ml and 750ml of water is 150 grams. The difference in how often you hunt for a tap is about half.
How to pick between 470, 600 and 750
Three honest questions, in order.
Where does it live? If the answer is a handbag or a small bag pocket, 470-600ml. If it is a desk, a car cup holder or a gym bag, 750ml. A 750ml bottle in a handbag gets left at home within a fortnight, and a bottle left at home is worse than no bottle.
How often can you refill? An office with a water point every twenty paces makes 600ml sufficient. A commute, a site visit or a day of meetings does not, and 750ml buys you out of planning around it.
Hot or cold? If you are carrying tea or coffee, 600ml is already a generous two cups and a bigger bottle just means colder coffee at the bottom. If it is water, bigger is strictly better.
Disclosure

Frequently Asked Questions
Does HYV make a 500ml water bottle?
No. The nearest sizes are OpenFlow at 470ml (₹999), ChillSip and DailySip at 600ml (₹1,199), and a 750ml tier starting at ₹899.
Why are there so few 500ml insulated steel bottles?
Double-wall vacuum construction adds 8-10mm of wall thickness. A steel bottle holding exactly 500ml ends up the external size of a 750ml plastic one, so manufacturers build 470-600ml or 750ml instead.
What is the best replacement for a 500ml bottle?
600ml. ChillSip or DailySip at ₹1,199 replaces a 500ml plastic bottle without feeling larger in the hand, because the extra capacity goes into height rather than width.
Is 600ml enough for a day?
For a desk day with a water point nearby, yes. For a commute, a site visit or the gym, 750ml is the size that stops you planning refills.
