bubba Envy S Stainless Steel Tumbler with Clear Lid, 24 oz.

I absolutely love this cup. There is such a trend for other brand name cups that are so expensive, we thought we would buy this off brand (for about $20 less) and see if we liked it. The first day, I stuck the cup on the patio at 6 am with lid in place. The temperature outside reached 95 degrees that day. At 6 pm, there was at least 3/4th's of the ice still remaining. Since I didn't do a true scientific experiment I can't give exact quantities. We have Yetti cups, Ozark Trail cups and Bubba cups. In my opinion, they all rank similar. They all hold ice for as long as anyone would be drinking the same drink! I have left a frozen drink in my Bubba cup overnight, and the drink is still frozen the following morning! I also love the fact that it comes with a straw. The other cups (we have) did not. You can buy a straw and lid for an extra $9.99 for the Yetti. I haven't found a straw lid for the Ozark Trail cup yet. The Bubba cup is a great product.
