Triple Aught Design
Vortex Pants
At the heart of its design is Polartec® Power Grid™, a cutting-edge, two-component knit fabric engineered to maximize warmth, reduce weight, and accelerate moisture wicking. This specific Power Grid weight offers exceptional versatility: warm enough for cold-weather missions, yet breathable enough for intense activity. This makes it the ideal base layer next to the skin for cold starts, sustained efforts, and long hours of operation in unpredictable environments.
Its cut is tailored yet carefully designed. Sufficiently articulated to allow natural movement under load, while remaining comfortable in camp, its silhouette combines technical performance with everyday practicality. A slightly shorter inseam prevents chafing with boots and knee-high socks, and eliminates creases at key contact points.
Its durability is enhanced where it matters most. Amphibious nylon reinforcements at the knees provide increased abrasion resistance for kneeling, climbing, and long days on rough terrain, extending the lifespan of these pants designed for heavy and repeated use. Flat seams minimize chafing during extended wear, while mesh-lined hand pockets offer convenient storage for lights, knives, or a phone when removing outer layers.
An integrated elastic waistband with internal drawstring ensures a secure and discreet fit under jackets and harnesses, and a faux vertical fly preserves the aesthetics of the pants without unnecessary bulk.
Made in the USA and designed specifically as the final piece of a complete technical underwear kit for expeditions, the Vortex pants offer optimal adaptability, whether worn layered or alone during slower phases.
