The Quantum might just be the most versatile jacket in the Flylow line. The 3 Layer fabric feels like a million bucks and it sheds water like a billion. Flylow packs in the features to include everything you want and nothing you don’t. The helmet compatible hood features a three point synch to get you just the right fit. There are great pockets in and out to carry all the essentials with you. The no-bulk cuffs feel great when you have them tightened down. The Quantum Jacket is one hell of a shell and it performs even better than it looks.
