"What Our Gearhead® Experts Are Saying: ""This is the jacket I grab when I’m not sure what the weather’s going to do. The waterproof shell keeps me dry on storm days, the insulated liner is warm enough to wear alone in the lodge, and together they’re toasty without feeling bulky. The underarm vents and helmet-compatible hood are perfect for long ski days."" From blustery storm days to bluebird groomers, The North Face ThermoBall Snow Triclimate Jacket is built for complete versatility on the mountain. This 3-in-1 system combines a waterproof, breathable DRYVENT™ 2L shell with an insulated inner jacket, letting us adapt to changing conditions. Worn together, they create a warm, weatherproof layer for stormy days, while the shell alone handles wet spring rides and the liner works perfectly for chilly après-ski walks. The shell’s recycled polyester construction is reinforced with a non-PFC DWR finish for eco-conscious waterproofing, while underarm vents and a helmet-compatible hood make it mountain-ready. Plenty of pockets—including a wrist pass pocket with a goggle wipe and large internal mesh drop-ins—keep essentials close at hand. The insulated liner uses THERMOBALL™ in the body for wet-weather warmth and HEATSEEKER™ Eco in the sleeves and collar for extra comfort and mobility. With a snap-down powder skirt, adjustable cuffs, and drawcord hem, the ThermoBall Snow Triclimate is ready for any forecast."
