I wanted a durable sustainable large light bottle and found these ones from Spain. Large dog and me consume a lot of water so I opted for a one liter single walled that would still fit in my bum bag bottle holder. Despite not a thermos it keeps refrigerated water cold for at least an hour or more in the current 28°C heat so I’m happy.
