The season when hydration is essential when going out. However, stainless steel bottles with a cold insulation function are a little bulky to carry around.

The "Gel Cool Bottle" found at the 100-yen shop "Can Do" is a slim pouch-shaped drink bottle. Pouch-type bottles are often seen, but the point is that they also come with a "cold gel".




If you freeze the bottle in the freezer, the gel acts as an ice pack and keeps the drink cold without diluting it. When I put water at room temperature as a test, it immediately dropped to the temperature of cooling in the refrigerator.



The capacity is about 400 ml. It is also a nice point that the bottle becomes independent if you put a drink while opening the bottom gusset. However, drinks above 60 degrees Celsius and boiling water cannot be used, and the inside is difficult to wash, so it may not be suitable for drinks other than water.



Even if the gel melts, it stays cool for a while, so you can use it to cool down by hitting it against a hot body. Although you can't expect a long-term cold insulation effect, it seems to be useful in the summer when you want to reduce your luggage as much as possible. Why don't you easily carry it around by hooking it on your backpack or belt loop? The price is, of course, 100 yen (excluding tax).
