Designed with high performance double-wall vacuum insulation and 100% stainless, 18/8 food grade interior, Klean growlers keep beer, kombucha, or cold-brew coffee at their original, tap-fresh temperature and carbonation for hours on end. As always, the Swing Lok® Cap is removable, all stainless steel, and threadless for a tight seal and leak resistance. Features a large 1.75" (44mm) opening fits ice and is designed for easy filling and pouring. Shatterproof and won't break like glass. Electropolished interior doesn't retain or impart flavours. Double-wall vacuum-insulated construction keeps contents cold 24 hours. 32oz (946ml).
