Stay Cool in Sizzling Temps with the Armachillo Polo Tank When the mercury’s climbing high at 8 am, you know it’s going be a scorcher. Pop on our Armachillo® Polo Tank and stay cooler and comfier all day long. The soft, wicking fabric dries quickly and keeps odor at bay, and every fiber is infused with microscopic jade that dissipates heat on contact, creating a tank that truly feels chill to the touch! Plus, loads of Duluth details keep you feeling coolly confident in toasty temps. Like a functional front placket you can unbutton for extra ventilation, a shirttail hem for added coverage and ease of movement, a bra strap keeper that prevents straps from peeking, and princess seams that flatter your figure no matter how hot and sticky it gets.
