These growlers were designed with Thermo 3D ™ Double Wall Vacuum Insulation Technology to keep your beer cold for 24+ hours or hot for up to 12 hours, and preventing the oh-so-common sweat glass bottles produce. 

Their threadless lid seals in carbonation and the 18/8 Medical grade stainless steel doesn't transfer flavor & no metal aftertaste.
