"What Our Gearhead® Experts Are Saying: ""I was shocked by how warm and dialed this jacket feels on storm days. The insulation hits the perfect balance—super toasty without overheating—and the 20K waterproofing holds up when the weather really dumps. The side zip entry is clutch for getting it on over layers, and the vents dump heat fast on bootpacks."" We love how the L1 Aftershock Jacket fuses street-inspired attitude with mountain-ready performance. Its recycled polyester shell and 20K/20K waterproof/breathable membrane give us the confidence to ride straight into the storm, while the plush recycled lining and well-placed insulation deliver warmth that feels downright luxurious. Whether we’re weaving through snowy streets or pushing for one more lap, the Aftershock keeps us protected, comfortable, and looking dialed. On the mountain, thoughtful details shine. Underarm vents release heat on long traverses, the stretch wrist gaiters seal out spindrift, and the large mid-chest pocket offers grab-and-go storage for essentials. The jacket-to-pant powder skirt integration and adjustable hood lock everything down when conditions turn wild. From first chair to late-night wandering, the Aftershock stands out as a warm, capable anorak built for winter’s coldest missions."
