Nobby Pet Refreshing Water battle lid

The bottle cooler cover, with its cooling gel cells inside, provides the perfect refreshment on hot summer days. Before use, the cover should be cooled for around 30 minutes (e.g. in a cooler or freezer). As the cover is made of cold-insulating neoprene on the outside, the water remains pleasantly cool for 2-3 hours. The cooling bag fits standard 500 ml bottles and comes with a hook for attachment.
