“Bought two of these for Eco Tanka 600ml Mini's, 73mm Ø. These are an easy fit and the drawstring pulls tight just under the lid - perfect. The snaps are nice and tight too. As a comparison, the Eco Tanka 1000ml Trekka 80mm Ø also fits, very snug but totally useable.”
“Pouch is well made, but only suitable for narrow bottles, I have a narrow bottle with a neoprene sleeve and it is a tight fit. I found that is also a bit short in the body compared to my other bottle pouches.”
