How does Hydro Flask's 32 oz Growler keep your lagers, ciders, and pale ales cold and carbonated down to the very last sip? It’s all thanks to Hydro Flask's Fresh Carry System™ and TempShield™ double wall insulation. Can’t decide which kind of brew to bring? Grab two growlers! They’re small enough to toss in a pack (or hold in your hand) and feature a streamlined handle, which makes them easy to carry and even easier to share.
