In Las Vegas right now, where it is 106 degrees as I type this (not joking one bit), clothing that keeps you cool is a must.
Ex Officio boasts that it actually cools you down 5 degrees with its Sol Cool Ultimate Hoody. It ventilates the head, pits and sides. And it protects the wearer from the sun with UPF 50+.
The hoodies come in versions for men and women. They retail for $75 each.
