Nalgene Wide Mouth Cantene - 96 oz
I have two of these. They are surprisingly durable.
Price Paid: $10
I have two of these. They are surprisingly durable. I have used them in the winter and summer with no problems. I have dropped them and they don't break or burst. They roll up small and empty they are very lightweight.
I would definitely buy more of these and recommend them to anyone.
