Frequently Asked Questions
Every HYV bottle and tumbler is double-wall vacuum insulated — that is the construction that holds temperature, because a vacuum has no air 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 the lid is opened.
HYV makes BIS-certified bottles, certified to IS 17526:2021, India’s national standard for stainless steel vacuum insulated containers.
Bottles run 750ml (CoreFlow, FlipFlow, SlimPro, DualFlow, SnapSip) and 1 litre (LuxeSip, LuxeFlow, DualFlow 1L, MagFlex), plus a 2 litre MaxFlow. Tumblers run 470ml (OpenFlow), 600ml (ChillSip, DailySip) and 1.2 litre (HydroFlow, HydroPro, HydroMax, HydroPop).
Food-grade 304 (18/8) stainless steel, double-wall vacuum insulated. 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.
Yes. The tumbler range (ChillSip, DailySip, HydroFlow, HydroPro, HydroMax, HydroPop) is designed for hot as well as cold, with sealed sliding lids that hold heat and clip closed for a bag. The 600ml ChillSip is the sealed coffee-mug format specifically.
