Growlers are jugs made of glass, ceramic or stainless steel and are used extensively in the United States and Canada to transport draft beer. Typically breweries and brewpubs sell these Growlers in order to sell take-out craft beer. In recent years there has been a rapid growth in the popularity of Growlers as a result of demand coming in from craft breweries and home brewing.

Collectible Growlers are also gaining popularity Growlers were first made in the United States more than a century ago and since then have undergone change in design and shape. Nowadays a typical Growler is made of glass and has a screw-on cap or a hinged cap that can help to maintain a beer fresh for more than a week. Growlers are typically found in two sizes – 64 fl oz and 32 fl oz (also known as a Howler or half Growler). Some are also in size 128 fl oz.

Cozies for Growlers are available in a variety of materials and colors. The common materials used are Polyester, Viny, EVA and Neoprene. Colors are typically bright shades that are conspicuous and eye-catching. The material of the Growlers facilitates easy printing and advertisers can easily print logos and names of companies on the Growlers with any advertising message or branding. In this way Growlers serve as an ideal advertising platform. For this reason many advertisers and promoters use Growlers as giveaways at promotional events, expos and trade fairs. The contact details of any advertiser remain visible on the Growler for a long time and in this Growlers serve as an ideal medium for brand recall.

For advertising and branding companies, Koozie serve as an inexpensive and relatively cost effective advertising medium that gives high return on investment (ROI). The cost of a Cozie is not very high and if one looks at the additional efforts involved in branding a Cozie, then it is just the extra costs for printing that are involved.

Printing on Cozies is a very simple and straightforward process. All that advertisers need to do is to provide a print-ready PDF file of the artwork that needs to be printed on the Cozie. Printers then submit a proof to the advertisers for their approval and a sample of how it would look on a Cozie. Once the advertiser approves the proof, printing is done in bulk and the Cozies are delivered to the advertisers as ordered. Sometimes Cozies are also sold without any branding or messaging, but this is rarely seen.

There are different types of Cozies for Growlers that are available. Some of them are collapsible while some of them are available with a strap. Manufacturers of Cozies use different types of straps and rubbers to differentiate the quality of their Cozies from that of others. Some use a 1 ½ “wide strap that enables users to distribute the weight of the Growler Koozie and the beer contained in it. Some manufacturers use an extra-thick 5mm neoprene rubber in the Cozies as it provides more durability, washability, quality and insulation in the Cozie.
