Why 750ml Water Bottle Thermos ?
Drinkables play a major role in our life. We can live 4-5 days without food but can't live more than 2 days without water. So cleanliness of these drinkables, water, and storage containers is as important as their right intake quantity. Water gets infected very often and quickly in Plastic, Silicone, and other artificial cheap materials. On the other hand, the water stays clean and bacteria-free for a long time in Stainless Steel containers. So choosing the right water bottle/thermos is very important for our health.
Water thermos can be used to store/keep, water/other drinkables warm and cold for a long time. So choosing water thermos serves both the purposes of storage and temperature control of drinkables. You can store your drinkables as hot, cold, or at normal temperature.
Fully filled 750ml bottle/thermos doesn't weight too much and you don't need to fill it again and again during the day. You work in an office or study in college mostly in sitting posture. In this condition 750ml, water/juice/energy drink is enough for the whole day. But if you use 500ml bottle/thermos then you may need to fill this again and again.
All the Stainless Steel thermos listed below are quite strong, sturdy, and useful. All the listed bottles/thermos can also be used in self-defense against eve-teasers other than storage containers. But it would be better if it won't be needed because it can cause major internal injury if you strike somebody with great force.
Bottle No. 1 also has a cup that provides convenience in drinking. Bottle No.3 is quite easy to hold in hand. You can choose any thermos listed below as you like, all of them are quite good. Purchase links are also attached with them 🙂
We hope this water bottle solution will full-fill your requirements for office, college, and other outdoor activities 🙂
