The Beast 50 oz Tumbler from Greens Steel is a game-changer in the world of insulated drinkware, delivering unmatched performance, durability, and style. Crafted from premium 304 18/8 food-grade stainless steel with a robust powder-coated finish in Army Green, this tumbler is built to withstand the rigors of daily use, from morning commutes to outdoor adventures. Its double-wall vacuum insulation is exceptional, keeping ice intact for over 24 hours and hot drinks steaming for hours on end—outperforming even the most renowned brands. What sets the Beast apart, particularly when compared to Stanley tumblers, is its superior design and functionality. The Beast’s upgraded screw-on lid with a leak-resistant gasket ensures near-perfect spill protection, a step above Stanley’s lids, which can occasionally falter under pressure. The inclusion of two stainless steel straws (one curved for water, one wide for smoothies) and a straw-cleaning brush adds a level of convenience and eco-consciousness that Stanley’s bundles don’t consistently match. Additionally, the Beast’s welded handle is sturdier and more ergonomic, making it easier to carry its generous 50 oz capacity without strain. The tumbler’s electro-polished interior prevents flavor transfer, ensuring every sip tastes pure, while its dishwasher-safe design simplifies cleaning—a practical edge over Stanley’s sometimes finicky maintenance requirements. At 10.5” wide and 5” tall, it fits most car cup holders and backpack pockets, offering versatility for on-the-go lifestyles. The powder-coated exterior provides a slip-resistant grip and resists scratches, maintaining its sleek look through countless adventures. I’ve purchased this tumbler for all three of my vehicles because it’s so useful, and frankly, it’s better than Stanley in every way that matters—longer temperature retention, a more secure lid, and a more thoughtful accessory bundle. Priced at $35.00, the Beast offers premium quality at a competitive value, making it the ultimate choice for anyone seeking a reliable, high-capacity tumbler. Whether you’re a coffee aficionado, a hydration enthusiast, or an outdoor explorer, the Beast 50 oz Tumbler is a must-have that redefines what a tumbler can do. Highly recommended!

GREAT TUMBLER.... THE ONLY SET BACK IS THAT THE INSTRUCTIONS ARE INSIDE THE TUMBLER. TO OPEN THE TUMBLER ITS A TWIST TOP. i WAS TRYING TO POP IT OPEN SINCE IT HAS THAT POP UP LIP. I RETURNED IT THINKING IT WAS SHUT SEAL, NOT!!!! IT NEEDED TO BE TWISTED. i FIGURED IT OUT WHEN THE REPLACEMENT TUMBLER CAME AND i WAS FACING THE SAME PROBLEM ... I COULDNT OPEN IT. I WAS LIKE NO WAY, 2 DEFECTIVE TUMBLERS. I STARTED TURNING IT AND VOILA, IT OPENED. INSTRUCTIONS SHOULD BE PLACED IN THE BAG, NOT INSIDE THE TUMBLER.

Just got my 50oz Beast yesterday and I love it, it’s perfect for me cause I drink a lot of water through out the day, it keeps the water super cold and the ice doesn’t melt for a long period of time which I love. Having 2 straw options is great as well. Really happy with this purchase, my mom wants to buy one and I think I’ll be ordering another one for me as well!!!

Great colors (I ordered the yellow and Army green) and the finish is perfect! The insulation works great! The other day I poured my coffee at 8am and didn’t get back to it until 11am and it was still nice and toasty. And that time in between included a car ride and several meetings and I was impressed when I found it to be nice snd warm. I will totally order this again!

UPDATE - After contacting Greens Steel w/photos, they've reiterated the interior is NOT coated with anything, but what is happening is apparently a manufacturing defect & will replace it at no cost to me. We shall see how the next one holds up. Otherwise, I really loved this cup because it kept my ice water cold all day! ORIGINAL REVIEW UPDATE: Before purchasing this item, I reached out to the manufacturer to confirm this drink cup was SOLID stainless steel inside and NOT painted because I've had numerous other ones peel over time, which is not only gross, but is a health concern. They assured me - in writing - these were NOT painted. Well, they lied because the interior bottom has started to chip/peel, which means it IS painted on the inside. So incredibly angry & disappointed - especially for this price point and the fact I also spent the additional money for their handle. Not to mention specifically asking BEFORE purchasing! Needless to say, I'm going to stop using it and throw it away, which is money wasted!

40 oz is my most used size of tumbler. The Beast holds heat and ice well. I like to make tea or other drinks that will last several hours. There is still ice in the Beast the next morning. The lid fits snugly and doesn't leak. Great product.

I ordered the 42oz Cupcake Pink tumbler and I was skeptical because I've had trouble finding a good cup that won't leak. As soon as I got this one I tested it out. No leaks! I haven't tried it with the straw yet because straws are aggravating but I love that they included the cleaning brushes for the straws. It kept my drink cold at work all day, never leaked, no metal taste, is easy to carry, and fits perfectly in my cup holder in my car. I love the color: it's a fun summer vibe and I can't wait to hit the beach with it. I would recommend this brand to everyone. Why pay almost $50 for a Stanley?? Not me! The Beast is where its at!

Keeps drinks very cold. I drive nights. I get home, leave it in my truck, windows up all day. And still has ice with the water in it the next night
