It seems to be active in the summer outdoors. Introducing the "folding bottle" of the 100-yen shop Daiso.
Daiso Folding Bottle
A plastic drink bottle with a bellows structure. When you drink the contents, you can fold it to about 1/3 of the size.
The capacity when unfolded is about 300 ml. The heat resistance is 60 degrees and it is not suitable for hot drinks.
There are two caps, a clear outer lid and a colored inner lid. The inner lid is a type that allows the contents to be sucked out when the head is pulled up. If you want to go very much, you can remove the inner lid and drink.

With a carabiner, it can be attached directly to a backpack. It is convenient to pick up quickly.
A bottle that seems to be useful when you want to proceed while reducing your luggage as much as possible, such as when traveling or outdoors. Check it out if you value lightness.
