When the weather's hotter than a mouthful of habañeros*, wear a cool-to-the-touch Armachillo® Longtail T® Tank instead of cotton. The 92% polyester/8% spandex knit is lightweight (just 4.4 oz./yard), soft, comfortable and quick drying – but what's really amazing is this shirt's Made-in-the-Jade™ technology. Every fiber is infused with microscopic jade that dissipates heat on contact. So this cooling tank feels chill to the touch – even on days so hot the hens are laying hard-boiled eggs.
