Vacuum flasks come in various sizes from 350ml to 2 litres. The most popular ones range in between 500ml to 1 litre. This is because they suit the requirements and also are easy to carry. A 1 litre thermos bottle is the ideal choice most of the buyers in India make.

• Leak-proof

The maximum heat retention a thermos bottle in India gives is 24 hrs. Brands promise this time limit, but hardly some make it truly. You will get bottles capable of retaining hot drinks as well as cold drinks. Most of the insulated flasks are capable of retaining cold temperatures for a long time as compared to hot ones.

Based on the quality, it is possible that the temperature retention time limit gets reduced as the bottle gets used up more & more. Lookout for Double walled & vacuum insulated thermos bottles because they will retain temperature for the maximum amount of time. Also, the stainless steel body helps. 12 hrs hot and 18 hrs cold is the ideal temperature combination.

Stainless steel body is preferred over plastic/metal/glass bodied thermos bottles. The reason being their capacity to retain heat for a longer time. Also, lookout for 304 grade stainless steel as it is the best quality. Its benefits include corrosion-free, BPA-free, and 100% food grade.

Then, the build should be strong to avoid scratches and dents. Also, it helps it last long. Lookout for lightweight thermos bottles as they will be easy to carry while travelling/trekking/hiking/etc.

Go for the one which can be used both as a thermos bottle and vacuum flask so that serves purposes of both drinking and storing. Most of them have flip lids for this. There are also only thermos bottles which you can opt for. Thermos flasks have cup-like lids so you can use that for drinking.

Most brands give a warranty of 1 year, but there are some which offer 3-5 year warranty. 2 year warrantied thermos bottles are rare to find.

• chompsky says “Despite compromises on design or prices, for my own use I prefer Anjali. As they have better control on things and making it themselves (Works near Bombay itself)”.

• panchabhut says “Milton thermosteel screw lid. (option not available) The flip lid loses temperature earlier”.

• Sidhu634 says “I have tried milton, cello, Borosil, and a few local brands. All of them work fine for a few months, after that efficiency drops. My brother has been using a cello hot and cold 500/550ml flask for around 3 years and it works fine. Whereas I bought the same bottle last year and it only keeps water warm for 2 hours only”.

• LIMBO says “Milton works well for keeping stuff hot for 24 hours. That too with ambient temps. mostly cool throughout, this year being a scorching exception. Although after some years of use it looks like it’s down to 18 hours or so. I rely on the flask on a daily basis as well as otherwise water here gets a tad too cold to suit me”.

• lanny25 says “Eagle Flasks are the best. Offers 5 years warranty on the efficiency. Have been using one since 2012, still going strong without any issues. The efficiency now might not be as good as new but still is able to keep my water chilled for a full day. Would suggest to try once, you wont regret it”.
