Familiarity: I've used it several times
When you're at the crag all day long you are going to want to have a cooler. This is perfect for some extra water, beverages, and food. Throw it on like any other backpack and walk right up to the wall. Climb hard all day knowing that you've got cold drinks and tasty snacks waiting for you no matter how hot it gets.
