Summer in the National Parks is all about milking every second out of the day. From watching wildlife to summitting peaks to climbing in the desert and jumping in alpine pools, the rawness of the National Parks is something to be enjoyed and respected. Fluctuating temperatures require gear that can handle the heat, but also perform in the cool of the night. In Yellowstone National Park, temperatures can range from the 70's down into the 30's - all in the same day! In more deserty parks like Joshua Tree, temperatures often are in the high 90's in the day and cool off to 60 at night. We snooped around to find local brands who can make sure you are ready for your trip this year.
