Travel Water Bottles
Frequently Asked Questions
Every HYV bottle is double-wall vacuum insulated, which is the construction that actually holds temperature — there is no air gap for heat to travel through. Cold retention runs up to 24 hours and hot up to 12, depending on the model, how full the bottle is, ambient temperature and how often you open the lid.
Yes. HYV's certified range spans both bottles and tumblers — the 1L LuxeSip, LuxeFlow and MagFlex, the 750ml CoreFlow and the 600ml ChillSip — all tested to BIS IS 17526:2021, India's national standard for stainless steel vacuum insulated containers. That means the insulation performance and the materials were laboratory tested rather than simply claimed. BIS is granted per product, which is why the certified models are named here rather than left vague.
Bottles run 750ml (CoreFlow, FlipFlow, SlimPro, DualFlow, SnapSip), 1 litre (LuxeSip, LuxeFlow, DualFlow 1L, MagFlex 1L) and 2 litres (MaxFlow). Tumblers are 470ml (OpenFlow), 600ml (ChillSip, DailySip) and 1.2L (HydroFlow, HydroPro, HydroMax, HydroPop).
Food-grade 304 (18/8) stainless steel with double-wall vacuum insulation. There is no plastic liner and no BPA question — steel is inert, so it does not leach and does not carry taste between uses. Lids use a removable silicone gasket so the seal can be cleaned properly.
A sipper cap suits desk and meeting use, a wide chug cap is faster to drink from at the gym, an inbuilt straw means you never tilt the bottle, and the MagSafe magnetic lids snap to a phone mount. DualFlow gives you a chug spout and a sipper in one lid if you would rather not choose.

Travel asks two things of a bottle that daily use never does: it has to survive being packed, and it has to pass through an airport. A bottle that leaks at a desk ruins a notebook; one that leaks in a cabin bag ruins everything in the bag.
So the useful features here are unglamorous. A lid that seals under pressure changes. A diameter that actually fits a car cup holder rather than almost fitting. A body that does not sweat, so it can sit against clothes. Insulation that holds through a long transit, because the next cold drink might be six hours away and cost four times what it should.
On flights: an empty insulated steel bottle goes through security in your cabin bag without issue — it is the water that is not allowed, not the bottle. Fill it at the fountain after the check and you have skipped the airside price entirely.
