The Giro Men's Ambient Cycling Jacket was created to slice through the chill on wintery mountain bike rides. But it's quickly become a favorite for urban commutes and a go-to staple off the bike too. This hooded jacket is a cozy wonder of warmth with a 4-way stretch, 3-layer windproof material that's backed with a thermal fleece for insulation. The 10,000mm waterproof rating helps to shed water easily, and wrist gaiters help to seal in dry warmth while enhancing fit with winter gloves. Zippered hand pockets add versatility and comfort when you're off the bike, and genuine 3M Reflective details enhance visibility day or night. The hood is helmet compatible and will pull over most helmets.
