I can understand where your coming from to a point, I’ve been on this forum for a while and I read more then I post. I felt a new thread would help my decision more then an older one. I’m sure you are a lot more active here then I am and see more multiple repeat threads then I do. I’m going to take the advice of the first response and order the amazon link, thank you for that!!
To respond to the hydo flask option, I do currently have one myself that I use for water but never considered using it for coffee. I fear using mine for coffee for 3-4 months would leave a little bit of the taste in it when I would switch back to water in the spring l, they are costly so I don’t think I will invest in one to dedicate for winter when there’s a more cost effective option available, but thank you!!!
