What Our Gearhead® Experts Are Saying:"This vest is my go-to for warm weather hikes. The recycled polyester fabric feels soft and lightweight, and the ventilated design keeps me cool even when pushing the pace. The Polygiene® treatment is a bonus for staying fresh on multi-day adventures. It's perfect for layering over a sports bra or as part of a lightweight layering system."The Women's Wisp Vest is crafted for those sun-drenched trails and fast-paced summer treks where staying cool and comfortable matters most. Designed with a lightweight, recycled polyester fabric, it balances densely woven and open-knit sections to provide a semi-opaque style that ensures excellent airflow without compromising coverage. Low-bulk seams reduce chafing under a pack, while the racerback cut offers complete freedom of movement as we tackle challenging inclines or savor long, scenic routes. The Polygiene® silver ion treatment ensures we stay fresh no matter how far we go, making it an essential piece for both short day hikes and extended adventures. Sustainability features like fluorocarbon-free fabric and 95% recycled materials make this a vest we can feel good about wearing, too.
