AH_5645af21-11ec-11ea-a226-0cc47a40fa97Lightweight metal water flask.
You should drink water so it is advisable to always carry it with you.
To take care of nature and refrain from buying that silly plastic, we have a flask with the logo of Aviatsiya Halychyny.
The lid is tightly screwed; the flask has a silicone insert inside so that water doesn’t leak. On top of the lid there is a special loop with a carabiner, so it is convenient to cling the flask to a bag or a backpack.
