Caught the Bug
We like to hike a lot and since I picked up a new Sling pack i would carry my dogs canteen in it. Well, it is one of those flip ones you can pour water into dish while it being connected. I am looking for a better one that is more durable. These keep breaking especially when I drop them by accident. I am looking for ideas. I would like one that I can freeze with partial water in it like my Camelbak hydration bladders. Any and all ideas welcome.
The ones I use are similar to below.
