I bought this Yeti Knockoff last week and it just arrived yesterday. It is called the Magnum Steel 12 oz. Jacket. It is a little different than the RTIC and Ozark Trail. This one has a shorter sleeve at the top.and the can part is a little taller. It keeps the beer cold pretty much exactly like the others.
Here is another Yeti Knockoff I found today. It is the
Marky Products Stainless Steel Tumbler 24 Hour – 20oz Multipurpose Premium High Performance Double Wall Vacuum Insulated 18/8 Food Grade Cup. It is available on Amazon for $14.98 with Free Shipping.
It looks to be exactly like the Yeti, RTIC and The Ozark Trail from Walmart.
