I had been using the Titan Deep Freeze 30 Can Ice Wall Backpack Cooler over 3 years now and loved it! I purchased from Costco. However my backpack cooler this does not offer leak proof zippers. I do like the sturm strip a lot I wished it has hip strips too. I was hoping to see that this new model Titan Deep Freeze 24 Can Welded Backpack Cooler has it but apparently it didn't. I hope to see that in the next model backpack cooler. Othen that I really think this new Titan Deep Freeze 24 Can Welded Backpack Cooler looks great. Saw at Costco the other day and I wasn't sure about getting one until now after this video. Also I want to say I love Titan cooler products. We have new model ranging from little lunch boxes (I bought a few of these to give to my nephews and niece each new school year, since the kids beat it up pretty badly after a years uses) to the larger Deep Freeze 60 (50+10) Can High Performance Rolling Cooler.
