“Took a trip to Port Aransas Texas with my dad, brother, and uncle. Parked the truck in the parking lot and went on an 2-day offshore trip. We had a blast and came home with a full box of wahoo and yellowfin tuna! Walking out to the truck after we made it back to the dock I noticed something was missing. My heart sunk! My Yeti 45 was stolen off the truck! I had that cooler for 6 years, it had been with me all over the country working on pipelines! We looked all around the town, my cooler had all kinds of stickers from everywhere it would have been very noticeable. Needless to say we never found it. Now I have a DENY Lock and leave my cooler on the truck all the time like I did my old one, but now they can’t get it! ”

“Went fishing for the day on the lake and left my 65qt in the back of the truck as I always do. That evening we came back to the dock ready to fill the cooler up with catfish we had caught, and it was gone. I have never had anything stolen from me like that before, what a gut punch! My new cooler will have a DENY Lock!”

“I used to have 3 Yeti coolers in my garage. On weekends I have the garage up working on things. I never thought that someone driving by would be actually taking note of what they saw in my garage but they did. I guess the Yeti coolers stuck out like a sore thumb. We went to eat dinner and when we returned they had sprung the garage and got my coolers. Now the only place I keep my cooler is in the back of my truck with my DENY Lock. I leave the tailgate down just to see if they will come and try to steal it, no takers!”

” We hunt public lands and have never had a problem with theft. Just so happens the weekend we went and got a good deer, quartered up and ready to put in the Yeti! Looked in the back and it was gone! We almost lost the meat due to the heat on the way back to town to get another cooler and ice. We have a DENY Lock now, and we also have our cooler!”
