The Siren Bib gives you a lighter weight and extra breathable bib top for backcountry missions. Thanks to Flylow's proprietary Intuitive™ Perm fabric for utmost air permeability, you won’t sacrifice durability or wet out. The air permeable fabric is designed to keep you cool by releasing heat before you sweat. 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.
