Tru-Spec's new line of Cordura brand baselayer undergarments are manufactured from a 60/40 cotton/nylon jersey knit that's more comfortable, protective, durable, and versatile than 100-percent cotton. The soft, moisture-wicking, no-melt fabric is also protected with freshFX fabric technology for lasting freshness. Cordura brand baselayer undergarments by Tru-Spec are available in seven colors in briefs, long drawers, short-sleeve and long-sleeve crew necks and mock neck. All colors are not available in all styles. Sizes range from Small to 3XL.
