After getting a phone call from 4x Super Bowl Champion Rob Gronkowski requesting a jug that would keep his water cold all day to help him stay hydrated through summer practices in Tampa, FL, we came up with the perfect solution - the Ice shaker One Gallon Jug! Constructed from premium, kitchen-grade stainless steel, the Ice Shaker One Gallon Jug wil not absorb odors, will not leave behind a metallic taste (unlike most metal jugs and bottles), and is double wall vacuum insulated to keep your drinks cold for 60+ hours and prevent condensation from building up on the outside of the jug. For easy sipping, the One Gallon Jug comes with our Sport Straw that regulates the flow of liquid so youre only taking in as much liquid as YOU want!

Take your hydration to the next level and keep your water ice cold all day with an Ice Shaker One Gallon Jug.
