My family - partner, soon to be 9 and 6 year old kids and me - will spend 7-8 weeks car camping in national and state parks across the country but focusing much of our time in Arizona, New Mexico and Southern Colorado. 

This will be our 4th big summer car camping and we are finding that we increase our efficiency, comfort, and enjoyment with each campsite. 

We have decent gear for camping and food prep but I am concerned about outfitting ourselves for the heat and sun in the southwest. I have been reading blogs and fully anticipate hiking in morning and evening but still, what are the best quality, most effective clothes, hats, shoes, swimming gear, etc. for all of us?

I wish we could go to an REI location and have an expert dress us properly...
