1. Milton Elfin Thermosteel Flask

This Milton flask is the top rank in our list and a highly purchased product in 2021 as it has amazing features. The bottle is 100% leak-proof and ensures you can carry it anywhere without any worry.

But the notable downside of this flask is that its heat retention duration is 12 hours only. Though, the brand claimed it 24 hours. Despite that, we loved this purchase and would love to recommend it to everyone who's looking for a sturdy and best thermos flask in India.

2. Cello Swift Stainless Steel Double Walled Flask

Our next pick is made using thermo-seal technology. The sleek and compact design with a wide mouth is very easy to use and clean. For better heat retention, the inside of the flask has a copper coating. The classical color adds a unique touch to the flask.

But the cost is a bit higher than other picks. However, on the quality front, it is worth big thumbs up.

3. Borosil Hydra Thermo Stainless Steel Flask

Equipped with a double-wall vacuum with a copper coating, this flask also features good heat retention. The main notable feature is that all the plastic parts are BPA and phthalate-free. In addition to its specifications, the bottle also comes with a nice cover. The available sizes of the bottle are from 500ml, 700ml to 850ml.

24 hours heat retention is a little bit overrated. It works well for up to 10 hours. However, build quality and lid quality are just awesome.

4. Milton Thermo steel Flip Lid Flask

Filling and pouring liquids is totally hassle-free. This must-have thermo-flask is made using high technology that offers sturdy durability. But the temperature retention capacity decreased after 2 months.

Still, it delivers a good performance. Overall, it is a nice product at a great price.

5. Amazon Brand - Solimo Stainless Steel Insulated Flask

This popular bottle in India is made from 100% food-safe, 304-grade stainless steel. This is a pretty easy-to-use flask. The notable features are rust-free, BPA-free, leakproof cap, wide-body and tapered mouth, and condensation-resistant body with a sling cover.

The bottle is a bit heavy but on the front of durability and portability, it is a valuable product.

6. Milton Glassy Thermo Steel Vacuum Flasks

Our next pick with a 1000ml capacity comes with a well-insulated mechanism. The inside and outside of the bottle are made using 18/8 quality stainless steel. The bottle has one minor design flaw that is its flip lid doesn’t have a rubber seal.

It can cause water to drip from the gaps of the flip lid. This apart, it is best for juice, cup, or coffee.

This three-layered stainless-steel bottle provides excellent performance and you can keep your beverages hot for up to 12 hours. The bottle is ideal for daily use.
