Greens Steel Beast 40oz Tumbler — Stainless Steel Vacuum Insulated
💬 Why Jason Recommends This
The Greens Steel Beast 40oz Tumbler is Jason's daily driver — and it earns that title. Double-wall vacuum insulation with a copper lining keeps drinks cold all day long, and the splash-proof pop-up lid seals tight enough to toss in a bag. Made from premium 304 18/8 food-grade stainless steel with a powder-coated finish that won't fade. Comes with 2 unbreakable straws and a straw brush in a beautiful gift box. Backed by a lifetime guarantee.
“This is the tumbler I grab every single morning. Keeps my coffee hot for hours and my water ice-cold all day. The lifetime guarantee sealed the deal for me.”
