Innovative Cooling Pack for Cooling Vest for Dogs (S)

Please make sure to choose the same size of ice pack as the vest. If you choose a different size, it won’t be effective because it doesn’t fit the size of vest’s pocket.
Lab Results: after 1 hour at 90F (32C), surface temperature was still 41F (5C)
STRONGEST cooling power: Cooling power lasts up to 3-4 hours with surface temperature below 59F (15C)
Please make sure that the blue part is facing the dog’s body and insert it in the vest pocket.
The blue part becomes whitish and completely frozen. Use in this condition is most effective.
