Stood the test of time
Will take this to the crag or on a backpacking trip for a bit of extra fun. It’s super durable unlike others I’ve had that would leak at the seams. Holds much more due to its creative shape than other 8oz flasks
Not my favorite flask in the cabinet. . .
I got this flask because it was bigger then my current one and i like the look of it. I don't love this one because it gives your liquids a metallic taste. So it is not my go to.
