Verdict
An air-conditioned shirt? The proCOOL claims to chill skin by 5.8°F—a lofty promise. But during steamy indoor spin classes and warm-weather hikes, this short-sleeved crewneck truly did feel cooler than other shirts. The secret? Channeled, hollow polyester fibers that funnel air across skin and speed evaporation. An inverted Y-shaped mesh panel extends across the back, from below the neck to under the arms, for more venting in those sweaty zones. craft-usa.com

“This shirt proved less stinky than many synthetics, thanks to the silver- and titanium-based anti-odor treatment.”
