The Siren Bib gives you a lighter weight and extra breathable bib top for backcountry missions. Thanks to our proprietary Intuitive™ PHD fabric for utmost breathability, you won’t sacrifice durability or wet out. The Siren is streamlined and durable with simple design, so you can focus on the day’s objective. A kangaroo front pouch stores your essentials, outer thigh vents release steam, and reinforced cuffs and knees keep scuffs away.
