Gregg, I have the RTIC can koozies too and I love them. I also have a 30 oz Yeti, a 20 oz, RTIC, and a 30 oz Ozark Trails from Walmart. The Ozark Trail cup from Walmart was $9.99 and is every bit as good as the Yeti and RTIC brands. If you can ever find them get one of the Ozark Trail cups, you won't be disappointed. The problem around here is that Walmart sells out of every shipment they get with in a day of stocking them.
