Flylow made the Women's Siren Bib for ladies who like to spend more time walking uphill than they do riding chairlifts. Made using their most breathable fabric, the Intuitive Perm, the Siren Bib breathes easy, making it a great choice for long hauls on the skin track. Outer thigh vents let you quickly dump excess heat when you're working hard, letting you finish the summit push ahead of schedule. Once you're ready to drop, you can count on the low-bib design and 20k waterproof rating to keep you dry, comfortable, and ready to take another lap.
