Things to consider when choosing a suitable vacuum flask for trekking
Recently, vacuum flask has become an incredibly essential product since it is not only suitable for indoor activities but also for outdoors. Fond of walking long distances on foot for pleasure, make sure to bring a vacuum flask in order to stay hydrated. Here are several things to consider when choosing a suitable vacuum flask for trekking.
Heat keeping period
A vacuum flask is capable of retaining heat.
Usually, bottles keep the temperature for 8-24 hours, some can keep the heat for more than 24 hours or even 48 hours. If you go trekking, any bottle that can retain heat for 8 - 24 hours will be suitable. If you only play sports or gym, you should choose a vacuum flask that has heat retention of 6-8 hours.
The design

The vacuum flask has two parts: the lid and the body. There are two types of lid (inner lid and another outer lid). The function of the lid is to prevent steam and heat from leaking. The body of the flask has an outer shell which is often beautifully decorated and designed.
Most vacuum flasks are in the cylindrical shape and designed to be held by one hand. The shape of the flask’ body is also quite diverse, but the most popular today is the round-shape design from top to bottom.
The lid tightness
The lid is designed to close properly.
In addition to the material and the structure of the vacuum flask for trekking, a good gasket should also be in focus as it helps ensure that the bottle is tightly closed, without letting the heat escape.
However, in a direct purchase at a store, it is recommended to check the mounting part because it may be affected during transportation. Tight-fitting will prevent the water from spilling or leaking. With silicone seal gaskets, the products with the tightest fitting thermostats must be those with spiral mounting rather than simply push-ups (buttons/jacks).
Tank capacity and weight
The bottle is designed to usually hold at least 300 ml. Depending on the purpose of use, we can choose vacuum flasks with suitable capacity. If we need a personal vacuum bottle, its capacity will be determined by the volume of water we drink for a day. In simple needs, one person will need to drink 1.5-2 liters of water a day. Therefore, please avoid choosing bottles that are too small. If we pick a 750-ml bottle, we will need about 3 bottles a day.
The water tank capacity keeps the heat and the tank weight is proportional to each other. The larger the capacity, the heavier the bottle. If the bottle is too heavy, it would be a burden to carry around.
For people who plan to go for long walks, a vacuum flask for trekking, which usually has a capacity of 750 ml, will be optimal. For office workers, who have fewer movements, a larger capacity is preferred.
