What Our Gearhead(R) Experts Are Saying: "The Billie is the one shell I trust for everything-resort riding, touring, bootpacks. The 3-layer fabric is tough but breathable, and I love the clean fit. Plenty of pockets, awesome venting, and it's never let me down in a storm." From whiteout chairlift laps to spring summit missions, the Flylow Billie Coat is the do-it-all shell we trust to handle every turn the mountain throws our way. Constructed with Flylow's burly-yet-breathable Surface 3-layer hardshell fabric, this jacket is built to perform in the harshest conditions while offering the breathability we need for long bootpacks and sidecountry laps. With a 20K/20K waterproof-breathable membrane, PFAS-free DWR, and fully taped seams, the Billie keeps us bone dry in storm conditions. Thoughtful features like large underarm vents, a helmet-compatible hood, No Bulk cuffs, and a removable powder skirt let us dial in comfort across a variety of objectives. Multiple internal and external pockets provide easy access to essentials whether we're at the resort or far from the trailhead. It's technical, reliable, and versatile-everything we want in a shell built to go anywhere.
