Dual Performance

Dual Performance

Made in the USA utilizing two leading-edge fabric technologies from Polartec®, Atlas works equally well as a standalone performance base layer in warm weather or as part of a layering system in cooler conditions. Atlas balances moderate solar protection (SPF 30) with high breathability, and is built for long-wearing comfort.

Polartec® Delta™

Polartec® Delta™

Delta captures and retains moisture in pockets, while remaining cling-free. The specialized knit construction uses both hydrophilic and hydrophobic yarns to enhance convective heat loss, remain breathable, and regulate drying time.

Polartec® Power Dry™

Polartec® Power Dry™

Power Dry provides superior wicking action that draws moisture away from the skin. Drying twice as fast as cotton-only fabrics and staying 30% drier than other single-component fabrics, Power Dry is also comfortable, highly breathable, and easy to care for.

Anti Bacterial

Anti Bacterial

Atlas features Polygiene odor control technology, a silver chloride treatment which inhibits the growth of bacteria, keeping the garment fresh longer between washes.
