Overall I am pleased with the product, however there are some improvements I feel can be made to increase the quality. One of the koozies I received had the patch sewn on at a slant where as the other two I received were straight. I also made a stich on the koozies where the velco overlapped to ensure it would have a constant tight fit to the bottles I will be using it for. With no bottom, it seems likely that a bottle or can could possibly slip out if the velco doesn't remain secure.
