In prep for the summer heat, I decided to upgrade my Cool Shirt system from the 12 qt soft pack that I've been using for 5 years to the hard case 24 qt version. This should extend the cooling duration from 30 mins to around 1 hour in 95F heat.
If you're not familiar with these systems, they circulate ice water from a cooler mounted in the car through tubes that are woven into a shirt that is worn under your fire suit to cool your body while racing.
This system has worked REALLY well with the cooled hooded shirt (which gets the cold water under my helmet) and cooled pants, but I wanted longer duration. Once I get in the car and switch on the freezing water flow, its like having my own private a/c system.
I mounted the larger cooler by attaching the standard Cool Shirt cooler mount to a passenger seat mount that bolts to the factory seat mounting points. The cooler can be removed from the mount by the included velcro straps for easy emptying.
