The BFF Jacket II is a versatile 3-layer shell built with Flow 3L fabric — a wind- and waterproof membrane that is lightweight, stretchy, and silent. Fully seam sealed and equipped with water-repellent zippers, it handles everything from daily rain to mountain weather without compromise. The jacket features an adjustable hood, zippered underarm vents, articulated sleeves, and multiple pockets for practical carry on the move. Both the membrane and DWR treatment are completely PFAS-free, and the recycled polyester construction is designed to be returned and recycled at end of life.
