Great product and very well made, I recently bought one for my Geopress and I like it so much that I bought one for my UltraPress, Thank you

Perfect Companion Item

I love this idea! Although I may still want a larger millbank bag in the future, I think this is a perfect companion to the Grayl purifier. If I am out stomping around for a water supply, the water bottle bag will be right there with the purifier and not tucked away back at camp.
