The Milton Duo DLX 1000 is the best overall water bottle here, since Milton says it keeps drinks hot or cold for 24 hours. Buyers in India choose a water bottle by use: a plain steel bottle for daily carry, a vacuum-insulated bottle for hot or cold drinks, or a plastic bottle for a bag. The Milton Aqua 1000 is the plain steel option with hand-wash care.
The Borosil 700 ml is the one with a wide mouth and split hot and cold hours. The Milton Pacific 1000 is the PET choice. The Cello Puro suits cold drinks only.
The Milton Duo DLX 1000 Thermosteel Hot and Cold Water Bottle holds 1000 ml. Milton also lists 350, 500, 750 and 1500 ml. The body is 304 grade stainless steel with vacuum insulation between inner and outer walls. The screw cap has a flip lid that doubles as a cup.
Milton gives 24 hours of hot or cold. The inner copper coating is said to improve insulation. The maker describes a leak proof design and gives a one-year warranty.

Start with the drink. Plain water needs no insulation, so the Milton Aqua or Pacific will do. Tea and coffee need insulation. The Milton Duo lists vacuum insulation, and Borosil's name says double wall. Cold-only use points to the Cello. The best water bottle brand guide compares makers.
Then check weight and size. Milton lists weight and size for the Aqua. Cello does for its Puro. The others leave one or both out. For sport, our best sports water bottle and best gym water bottle pages go deeper.
Look at the lid and material next. A flip lid that works as a cup suits a commute. A wide mouth suits ice and easy cleaning. A silicone ring helps seal the bottle. Leak-proofing is listed for four of the five. Steel is food grade and rust-proof, according to Milton, and PET is recyclable. Other materials have their own pages, such as best copper water bottle and best glass water bottle.
Warranty is the last check. One year appears on the Milton Duo and the Borosil. The other three state none. See the wider bottles and flasks range for more.
The Milton Duo DLX 1000 is the best all-rounder. It has 24-hour insulation and five sizes. Milton also gives a one-year warranty. The Borosil 700 ml is the pick for a wide mouth. The Milton Aqua is the plain steel choice. The Pacific is the PET option. The Cello suits cold drinks only.
