Cowboys are known to be tougher than buffalo hide, but even they can get overheated while busting broncs or bulldogging heifers. For them (and you), we’ve created the Armachillo® Fence Mender Shirt. Its fabric is infused with microscopic jade – a natural mineral that conducts heat with amazing efficiency, making this shirt feel literally cool to the touch. What’s more, it wicks sweat to keep you feeling drier on long trail drives. And fights stink, so you won’t end up smelling like a dirty varmint after a day in the saddle. There’s even a vented back yoke with breathable mesh liner, so you can take it cool when you’re working where the skies are not cloudy all day.
