Embark on your dawn patrol mission or post resort pow day tour in the super lightweight FlyLow Siren Bib Pant. The heart and soul of these bibs is the air-permeable, stretchy, and waterproof Perm face fabric that is able to eliminate sweat by preventing overheating, while still keeping the weather off of your layers. To further keep you protected but moving effectively, the Siren also features a half-height bib, adjustable suspenders, and large outer leg vents that let you dump excess heat during extremely rigorous periods of time.
