    START WITH BEST

    The proprietary yarns used in our Fortis fabrics are spun from Ultra High Molecular Weight Polyethylene (UHMWPE) fiber blended with other polymers and knit to create a stronger, lighter, more durable fabric. UHMWPE does not take dye well which gives it a unique look and feel.

    CHOOSE YOUR WEIGHT CLASS

    Fortis 115 (90% Polyester, 10% UHMWPE) is ultralight and very breathable. It punches above its weight, matching the tear strength and abrasion resistance of heavier weight synthetic fabrics, and significantly outperforms common 250gsm merino wool fabrics.  

    Use 115 as a spring/summer/early fall light layer to cut the chill and protect from the sun. In cold temps wear it under a midlayer and shell for optionality when your aerobic output varies.

    Fortis 150 (90% Nylon, 10% UHMWPE) is our standard weight offering. Buttery to the touch, you would never know it contains the same fibers as body armor. Stronger fibers create a longer lasting garment.

    Use 150 year round as a more substantial layer than the 115 when you need a little more warmth or better sun protection.  

    Fortis 250 (80% Nylon, 10% UHMWPE, 10% Polyester) is our thermal weight offering. Knit with a beautiful french terry stitch.

    250 excels in all cold climates, wintry seasons, or when you just want a heavier option.
