Buy this combination 30oz ColdCapLid and an IcePack to keep your longneck bottled beer COLD! Tested in Texas so we know it works absolutely fantastic.
The IcePack and ColdCapLid (Cold-Cap-Lid) is as good as it gets. Keeps longneck after longneck refrigerator cold. When done return the IcePack into the freezer for next time. Keep several on hand in case your buddy shows up with a sixpack!
1 - IcePack for 30oz tumblers
1 - ColdPackLid for 30oz tumblers
Does not include the tumbler or the beer :)
*Tested and works with Yeti, Rtic and many other Tumbler Brands.
