There is a meaningful difference between a thermoware bottle that keeps your drink vaguely cool for a few hours and a genuine vacuum-insulated thermosteel bottle that maintains your drink's exact temperature — hot or cold — for over a day. The Pexpo Mayo 620ml in Baby Pink is firmly in the second category. Built with Tri-Ply vacuum insulation and a 304-grade food-grade stainless steel inner chamber, it keeps hot beverages hot and cold beverages cold for 24+ hours — whether you are carrying morning chai on a long commute, cold water through an all-day outdoor event, or a cool juice through an eight-hour work shift. One fill. One bottle. All day.
The tri-ply vacuum structure is the engineering core of the Mayo's performance. Three bonded layers create a vacuum-sealed thermal barrier that prevents heat from moving in either direction — the cold cannot escape, the heat cannot penetrate. The result is a bottle with zero condensation on the exterior — the outer surface stays completely dry regardless of how cold the drink inside is, so it never leaves water rings on your desk or dampens the inside of your bag. The Baby Pink finish sits on a durable, rust-proof stainless steel exterior that is built to maintain its colour and finish through the daily wear of regular carry.
The Mayo is built for everyday reliability without compromise. It is 100% leakproof and spill-proof — safe to place horizontally or upside down in any bag without concern. The 304-grade stainless steel interior is completely non-reactive, maintaining a pure taste and zero odour regardless of what you fill it with. ISI certified and Made in India, the Pexpo Mayo is a conscious choice for anyone looking to move away from single-use plastic, backed by a 1-year warranty against manufacturing defects.
The Mayo uses Tri-Ply vacuum insulation technology — three bonded layers that create a sealed thermal vacuum between the inner chamber and the outer body. This advanced structure keeps beverages hot or cold for 24+ hours, performing significantly better than single-layer PU insulation. Whether it's piping hot chai in the morning or ice-cold water at noon, it arrives at your lips at the right temperature.
The inner chamber is made from SS 304 food-grade stainless steel — the same grade used in food processing equipment and high-quality cookware. It is completely non-reactive to acidic and alkaline beverages, does not leach any flavour or odour, and stays hygienic and rust-proof throughout its service life.
The tri-ply vacuum structure completely eliminates heat transfer to the outer surface, meaning the bottle does not sweat or form condensation on the outside — even when filled with ice-cold water. No water rings on your desk, no damp bag lining, no slippery wet grip. The exterior stays completely dry at all times.
The Mayo features a precision-sealed leakproof and spill-proof lid that holds securely regardless of how the bottle is oriented. Carry it on its side, in an overfull bag, or on a bouncy commute — no dripping, no seeping, no mess.
The Mayo is made entirely from BPA-free materials. No bisphenol-A compounds are present in any component of the bottle, making it completely safe for daily use for adults, teenagers, and children. Safe hydration, every single day.
The 304-grade stainless steel interior is completely odour-neutral and non-reactive. It does not absorb or transfer any flavour or smell from previous drinks — plain water tastes like plain water, chai tastes like chai. No metallic aftertaste, no lingering odour between uses.
Both the inner chamber and the outer body are made from rust-proof stainless steel, built to withstand years of daily carry, regular washing, and the occasional knock or drop without deteriorating. The bottle maintains its structure, hygiene, and appearance over the long term.
The Pexpo Mayo is ISI certified, confirming it meets the Bureau of Indian Standards safety and quality requirements for drinking water containers.

Every Pexpo Mayo purchased is a direct replacement for hundreds of single-use plastic bottles over its lifetime. The durable thermosteel construction is designed to last for years, reducing plastic waste and supporting a more sustainable daily hydration routine.
The Pexpo Mayo is backed by a 1-year warranty against manufacturing defects, provided by Pexpo.
The Pexpo Mayo keeps beverages hot or cold for 24+ hours thanks to its Tri-Ply vacuum insulation technology. Actual performance depends on the starting temperature of the drink, ambient temperature, and how often the lid is opened. For best results, pre-heat or pre-chill the bottle by rinsing with hot or cold water before filling, and fill completely.
Tri-Ply vacuum insulation creates a physical vacuum between three bonded layers, eliminating the medium through which heat can transfer. This is a significantly more effective insulation method than PU foam insulation, which slows but does not eliminate heat transfer. Vacuum-insulated bottles retain temperature for substantially longer and completely prevent exterior condensation — something PU bottles cannot achieve.
No. The tri-ply vacuum structure completely prevents heat transfer to the outer surface, which means there is absolutely no condensation or sweating on the exterior — even when the bottle is filled with ice-cold water. The outside of the bottle stays completely dry at all times.
Yes. Unlike PU thermoware bottles designed primarily for cold drinks, the Pexpo Mayo is a genuine hot and cold thermosteel bottle. It handles hot beverages like chai, coffee, and warm water equally well, maintaining their temperature for extended hours.
Yes. The Pexpo Mayo is ISI certified, meaning it meets the Bureau of Indian Standards safety and quality requirements for drinking vessels. ISI certification provides independent assurance of product safety and manufacturing quality.
No. As stated in the care instructions, carbonated and alcoholic beverages should not be stored in this bottle. The pressure from carbonation can affect the seal and lid performance. The Mayo is designed for water, juices, tea, coffee, and other non-carbonated beverages.
The Pexpo Mayo comes with a 1-year warranty against manufacturing defects provided by Pexpo.
Wash by hand using mild detergents and a bottle brush for the interior. Rinse thoroughly and allow to air dry with the lid open. Do not put in a dishwasher. Do not place in a freezer. When not in use, keep the bottle uncovered to prevent any odour buildup inside.
The Baby Pink finish is applied to the outer stainless steel body and is designed to be durable for regular daily carry. Avoid using abrasive cleaners or steel scrubbers on the exterior, as these can damage the surface finish. With normal care, the colour retains its appearance over long-term use.
Yes. The Pexpo Mayo range is available in multiple colour options and sizes. The GD Sons listing features the 620ml Baby Pink variant. Other colours and sizes in the Mayo range may be available — check current listings for the full selection. All variants share the same construction, insulation technology, and features.
