ONE OF THE MOST COMMON COMPLAINT ABOUT MEN’S UNDERWEAR IS THE FABRIC: TOO THICK, TOO THIN, NOT SOFT OR COMFORTABLE. THROUGH EXHAUSTIVE TRIALS, WE’ve DEVELOPED the perfect blend and weight that makes our signature fabric extremely soft and lightweight with properties of industry-leading performance fabrics. IT IS ALSO UV PROTECTANT WITH THE HIGHEST RATED ULTRA-VIOLET PROTECTIVE FACTOR RATING AVAILABLE OF UPF 50+, MAKING IT AN AMAZING MATERIAL FOR OUR TOPS AS WELL.
