I received the koozies pretty quickly just like they were ordered

They seem to be a good fit for beer bottles nothing like a little wet suit to keep your beer cool and insulated

When i was offered a discount to review these i though well maybe my beer will be a little cooler longer

I wont say that you can just leave a beer outside in the sun and come back an hour later and it is still as cold as the refrigerator but i was surprisingly happy with how long my beer stayed cool enough for me to want to keep drinking it
