HI FINE CARE Wine Cooler Bag, 3.0 Liters, Beverage Insulator for Freezer, Vodka, Tequila, Refrigerator

Big enough for a bottle of champagne and ties on which is very handy to keep it in position.

We’ve had this a few days now and have used it a couple of times.It works well - keeps white and rose wines nicely chilled and it remained frozen for over three hours when we were sitting outdoors on quite a chilly evening enjoying the ambience. On the occasion we used it indoors at usual room temperature it remained frozen for about an hour and a half. Even after defrosting it will still do a good job chilling wine. Indoors it caused quite a lot of condensation - so sit the bottle on a napkin or saucer.I like the fact it snugly fits the bottle with the toggle securing it. Not sure why it has a velcro opening - it wouldn’t offer much size adjustment and it fits all bottles we tried without having to undo the velcro.Looking forward to using this on warm evenings outdoors.

This gel filled wine cooler sleeve has a hook and loop closure so is easily adaptable to the differing dimensions of sparkling wine or champagne bottles. This sleeve specifically designed for larger bottles kept a bottle of champagne, that had been pre-chilled in the fridge, really cold for at least 45 minutes before it was losing its effectiveness. Comes with drawstrings to give the sleeve a snug fit onto the bottle.
