The TXO 1.0 series is a true knockout. The specially designed knit yarns are embedded with both activated carbon AND Nano Silver for long-lasting Anti-Microbial odor protection. Each garment has a UPF rating of 50+ and is knit to be soft, breathable and quick-drying. The style of each garment begs not to be hidden, but the performance as a base layer is hard to beat.  Rest assured, the performance of this base layer is beyond belief.  Just don't expect them to do the dishes.
