The first thing you'll notice when you grab the Fortis 150 Long Sleeve Baselayer is the buttery soft hand feel. How can fabric made from the same base material as body armor and suspension bridges feel like this? The answer is in our proprietary blended yarns made from ultra high molecular weight polyethylene (UHMWPE) and the highest quality nylon fibers available. Our goal is to create apparel that lasts and this is the culmination of years of development to create a superior baselayer fabric.
