I bought the two silos because campmor had them real cheap.
The one with the American flag is from before they stopped using BPA. It had a Brunton button compass embedded in the lid that worked really well. Much better than the other button compasses I've seen. But that is long gone now. I had two 32oz hdpe's that I used a lot. But I have no idea what happened to them.
special note number one
backpacker magazine mentions that 32oz gatorade bottles weigh much less. So that is something to think about.
special note number two
I really like this except for the price:
