Sail through heat waves with ease in the pants that combine Armachillo® cool-to-the-touch comfort and maxed-out freedom of movement. The hybrid design pairs a stretchy knit waistband with 4-way flex woven fabric everywhere else – a combo that's as unrestrained as it is durable. Both fabrics boast Armachillo's heat-dispelling Made-in-the-Jade™ technology, with microscopic bits of jade infused in the fabric that actually reduce skin temperature. Better yet, we've streamlined the waistband and added a drawstring to fit any figure and lay flat under your clothing. Crouch Gusset and articulated knees let you crouch without feeling constrained, and snap tabs let you convert your pants to capris. Built-in UPF 40 sun protection blocks searing rays and an anti-odor treatment fights funky smells. Lower half feeling heated? Put the heat on hold and crank the cold with Armachillo Cooling Pants.
