A thermos flask or travel mug may seem straightforward to choose, until you need to consider capacity, closure, insulation time and cleaning. A budget water bottle may be perfectly suitable for water at the office, but unsuitable for hot coffee during a long train journey. Conversely, a heavy stainless steel bottle is not always practical if you are mainly looking for a lightweight bottle for everyday use.
The main pitfalls are:
An insulated water bottle or travel mug usually has a double-wall construction. Vacuum insulation limits heat transfer between the inner and outer walls. Do not just look at a marketing claim; check the stated conditions and limitations.
According to Mepal’s product information, the Mepal Insulated Bottle Ellipse keeps drinks hot for up to 12 hours and cold for up to 24 hours. The 500 ml version has a wide opening for ice cubes, while the 900 ml version offers more capacity for long car journeys or days outdoors. The product information also states that the coloured bottle should be hand-washed and that only the plastic parts of the lid are dishwasher-safe.
For coffee on the go, a smaller travel coffee mug may be more practical. According to the product description, the 275 ml Mepal Ellipse Travel Mug keeps a drink hot for 30 minutes. That is suitable for a short journey, but less so if you want to keep your coffee hot for several hours.
A leakproof water bottle should close securely in the conditions in which you intend to use it. So check the following:
According to the product information, the Meoky 24 oz Insulated Tumbler has a BPA-free lid design and a silicone tip on the straw. The description states that the tumbler is leakproof when the straw has been removed. At the same time, using it with hot or carbonated drinks is not recommended. This makes it particularly suitable as an on-the-go water bottle for cold drinks.
A stainless steel water bottle is generally sturdy and suitable for hot and cold drinks, but always check the instructions for the specific product. Stainless steel can also be heavier than Tritan or plastic. A reusable Tritan water bottle is often lightweight, transparent and easy to clean.
Mepal Vita water bottles are made from polypropylene and Tritan. According to the product information, they are BPA-free, suitable for carbonated drinks, dishwasher-safe and fitted with a wide opening for cleaning or adding fruit and herbs. The models are available in 500, 700 and 900 ml. Please note: they are not intended for hot liquids.

The wide opening makes cleaning easier than with many narrow-necked bottles. The lid closes with a short twist, but always check that it is fully tightened.
500 ml capacity, product weight of 136 grams, dishwasher-safe and, according to the product information, suitable for carbonated drinks.
Why it suits this profile: For anyone who wants to take hot coffee or tea to work, on a journey or during outdoor activities.
The product information mentions a safety lock and leak-resistant design. The lid and closure must be fitted correctly, so test this at home before carrying the bottle in a bag.
700 ml capacity, 304 stainless steel, one-handed operation and, according to the product information, keeps drinks hot for up to 15 hours and cold for up to 24 hours.
Why it suits this profile: A practical thermos flask for car journeys, cycling, the office and outdoor use when you want to enjoy both hot and cold drinks.
The wide opening makes filling and cleaning easier. According to the product information, the outside stays cool and dry; hand-washing the coloured bottle is still recommended.
Double-wall construction, 500 ml capacity, suitable for ice cubes and, according to the product information, keeps drinks hot for 12 hours and cold for 24 hours.

The compact size means you do not need to carry a larger bottle unnecessarily. According to the product information, all components are dishwasher-safe.
275 ml capacity, fits almost any cup holder according to the product information and keeps drinks hot for 30 minutes.
We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Its lifespan depends on the material, closure and maintenance. A stainless steel bottle can last for many years with normal use, but sealing rings and lid components tend to wear out sooner. Replace a component if it is damaged or no longer closes properly. Clean the bottle according to the product instructions and allow all components to dry completely.
This varies by model. According to the product information, the Mepal Vita water bottle is dishwasher-safe. For the Mepal Insulated Bottle, hand-washing the coloured bottle is recommended, while the plastic lid components can go in the dishwasher. THERMOS Stainless King models state that certain components are dishwasher-safe on the top rack, but with coated versions, hand-washing may be better for preserving their appearance.
Not always. A 900 ml or 1.2-litre bottle is useful for long days without access to a refill, but takes up more space and weighs more. For a short commute, 275 to 500 ml may be more practical. Choose the capacity based on your route, the space available in your bag and whether you have access to a cup holder.
