FlyLow Men's Quantum Pro Jacket
This stormproof, three-layer hardshell jacket will keep you dry and warm no matter the conditions.
The Quantum Jacket shows no weakness. It’s made from a burly Surface 3-layer fabric that’s built to block water and wind, which means it’ll keep you protected and dry no matter the weather on Glory Bowl or Loveland Pass. It can be easily layered for changing temperatures and it packs down, making it suitable for the backcountry or a road trip to wherever the snow is falling. Low-profile chest zippers store what you need and can be accessed with a backpack on, while intentionally designed seamlines move with you as you climb and descend. If you’re looking for a jacket you can trust for your next ski day, this is it.
