Lid - The lid on your thermos needs to be secure and effective. It shouldn't come off easily, it shouldn't leak and finally, it should be easy to clean. The lid should be easy to loosen and tighten and it should fit the flask perfectly. Some flasks come with stoppers to keep them closed, but these are often not as effective as these can end up with leaking problems. Screw caps are a better option as they are more likely to stay in place, but if you are buying online it is still important to check reviews as this is to ensure that the cap does fit the flask accurately.
Many of these lids can also be used as a mug, which is really handy if you're outdoors and you don't want to carry an extra mug with you. The thermos should be made from the same material as the thermal Flask and it should be able to retain heat in the same way. This will allow you to enjoy your drink at the temperature you want without it cooling too quickly.
Material - The material used to insulate your thermal Flask can have a big impact on how durable and long it lasts. Stainless steel is a common and popular choice as it is a durable, corrosion resistant and easy to clean material that retains heat well. Plastic and glass thermoses should be avoided where possible as they are more prone to breakage, they do not retain heat well and they can rust fairly easily.
You will also want to check how well your thermos insulates. If the flask is double-layered then it will stop heat escaping from your drink and if it is vacuum sealed then it will retain heat more effectively. It may be better to buy a vacuum-sealed thermos made from inferior materials than a stainless steel thermos with poor insulation, as the former may keep your drink warmer for longer.
Other features - When you are looking for a thermos, you may want to check and see if the bottle has a carrying handle as this will make it easier to hold and carry. The free carry bag will help prevent any spills messing up the contents of your bag. You may also want to choose a water bottle that comes with a money back guarantee or warranty. If you buy your thermal Flask online, it can be difficult to tell how well it will perform, even if you read all the customer reviews. A warranty is there to protect you because if you can't test the thermal Flask beforehand, you can send it back for a refund/exchange if it doesn't function as advertised.
