500ml is a common search and an uncommon product, because a double vacuum wall adds 8–10mm of thickness and the 500ml footprint ends up either too narrow to insulate properly or so wide it stops being pocketable. HYV brackets it instead: the 470ml <a href="/products/hyv-dualflow-insulated-water-bottle-with-chug-sipper-cap-710ml-black">OpenFlow</a> at ₹999 and the 600ml <a href="/products/hyv-chillsip-sleek-insulated-tumbler-for-hot-cold-drinks-590ml-dark-blue">ChillSip</a> at ₹1,199. If you wanted 500ml for a commute coffee, take the 600ml — the extra 100ml costs nothing in handling and buys a sealed sliding lid.
Key Facts
- A vacuum wall is two steel skins and a gap, which adds 8–10mm of outside width for the same inside volume.
- HYV makes no 500ml. The nearest sizes are 470ml (OpenFlow) and 600ml (ChillSip, DailySip).
- The 600ml format holds hot drinks 6 hours and cold 8; OpenFlow is the open format at 6 and 3.
- 600ml is about two large coffees — a commute plus a top-up without a refill.
- OpenFlow has a bottle opener built into the base, which is the reason to choose it over the larger size.
Why 500ml is rare in insulated steel specifically
In plastic, 500ml is everywhere. In vacuum-insulated steel it is awkward, and the reason is geometry rather than demand.
An insulated vessel is two steel shells with the air pumped out between them. That assembly is 8–10mm thicker than a single wall for the same contents. At two litres nobody notices. At 500ml it is most of the difference between a vessel that fits a bag sleeve and one that does not — so manufacturers either make the inside narrower, which hurts how it pours and how you clean it, or they let the outside grow, which defeats the point of choosing the small size.
The two sizes either side are where the compromise lands cleanly: a bit under at 470ml, a bit over at 600ml.
Which side of 500ml to take
Take 600ml if the drink is the point. ChillSip at ₹1,199 is the sealed commute format — a sliding lid that clips shut for a bag, six hours of heat, eight of cold. DailySip is the same size and price in Electric Pink, Powder Pink, Mocha Mint, Dusty Rose and Pink Marshmallow. In practice 600ml is a coffee and a half, which is the reason people who buy it stop refilling at 11am.
Take 470ml if the size is the point. OpenFlow at ₹999 is the compact one, in Indigo Blue, Midnight Black and Sage Green, with a bottle opener machined into the base. It is the least sealed thing HYV makes — 6 hours hot, 3 cold — and that is deliberate: it is a tumbler for a table rather than a vessel for a rucksack.
The question behind the size
Most people searching 500ml are not attached to the number. They are describing a shape: something that holds more than a café cup, fits one hand, and does not look like a gym bottle on a meeting table.
If that is the brief, the thing to compare is not capacity but the lid. A sliding lid opens with a thumb and closes flush, so the mug can go into a bag mid-commute. A screw cap seals better and is slower. An open rim is fastest and seals not at all. Pick that first, and the 130ml between the two sizes stops mattering.
If it turns out you want something you can carry all day rather than drink at a desk, you are looking for a bottle rather than a mug — CoreFlow is 750ml at ₹899 and holds cold for 24 hours.
Disclosure
HYV makes the tumblers named here, so weigh the recommendations accordingly. What you can check independently: HYV publishes no 500ml product, the prices and capacities above are the live ones, and the 8–10mm wall figure is a property of vacuum construction you can verify on any brand by comparing a single-wall and double-wall bottle of the same stated volume. Where HYV is not the answer: if you want exactly 500ml in steel, a single-wall bottle will give it to you in a slimmer body — you simply will not get insulation with it. HYV makes insulated steel bottles from ₹899.

Frequently Asked Questions
Does HYV make a 500ml travel mug?
No. The nearest sizes are the 470ml OpenFlow at ₹999 and the 600ml ChillSip and DailySip at ₹1,199. A vacuum wall adds 8–10mm of width, which is why 500ml is rare in insulated steel and common in plastic.
Is 600ml too big for a travel mug?
It is about two large coffees, and it is the size most commuters settle on because it survives the journey plus a top-up. If it feels large, the constraint is usually the base diameter rather than the volume — check that against your cup holder, not the millilitres.
What is the difference between ChillSip and DailySip?
Colour, mostly. Both are 600ml at ₹1,199 with the same sealed sliding lid. ChillSip runs seven colourways including Platinum Grey, Forrest Green and Arctic White; DailySip is the pink family.
Why does OpenFlow hold temperature for less time?
Because it is the open format. It is built as a desk and table tumbler with a bottle opener in the base, so it trades sealing for access — 6 hours hot and 3 cold against 6 and 8 on the sealed 600ml.
Does HYV offer free shipping?
Yes — free shipping on all orders above ₹499, anywhere in India.
