Cool & Carry Bottle Holders / Insulators

Fit all bottles and flasks up to 0,5 liter (a little more than a UK pint, and about a US pint). You can hang it from your belt or just put it in your bag - the material and the processing has made the Bottle Holders very insulating: cold water in a Dopper stays cold for 4 uur longer in our Cool & Carry on a warm Summer day, we tested it!
