Again, this depends partly on the pack and its dimensions, but it also depends on the size and shape of the drinks being carried, and the ratio of ice to drinks preferred. A commonly recommended ice to drinks ratio is 2-to-1, and some cooler manufacturers will list estimated drink counts based on that specific ice ratio. If the product description lists several cans capacity without a specific amount of ice, assume that this number is much lower when accounting for ice. For example, a cooler that can hold 24 cans without ice would likely have eight cans if using a 2-to-1 ice to drinks ratio. If capacities are unclear from the product description, try contacting the manufacturer directly to clarify or find the product locally to assess the capacity firsthand.
