Since it does not dew condensation, portability is very excellent.
By one-touch, it opens simply single hand.
It is very light and keeping warm and keeping cool are possible.
Rather than the conventional thing, since it becomes further easy to wash, it can be used very cleanly.
This canteen attaches and drinks a mouth directly.
If I have a seal kit of an optional spare set and purchased, it washes, can use by turns and is sanitary.
