What Our Gearhead(R) Experts Are Saying: "I wear the Reserve Slim Insulated Jacket on the coldest days because it's slim, warm, and still super easy to move in. The insulation isn't bulky, the stretch fabric keeps me mobile, and the 20K waterproofing means I'm covered in storms. The pockets are dialed for riders too-especially the Therma-Pocket that keeps my phone from freezing." We choose the Burton Reserve Slim Insulated Jacket when we want warmth and weather protection in a more tailored package. Built with a 20K/20K waterproof and breathable 2-layer shell, this jacket seals out storms while the low-profile synthetic insulation keeps us warm without adding bulk. The slim fit is flattering yet functional, with stretch fabric that lets us twist, turn, and carve freely. Rider-driven details make a big difference in comfort. Fully taped seams lock out moisture, while mesh-lined Pit Zips offer quick cooling on long hikes or warm afternoons. The Contour hood adjusts easily to fit over a helmet, and plenty of pocket options-including a chest Therma-Pocket and a sleeve pass pocket-keep our essentials safe and accessible. With Bluesign-approved recycled materials and PFC-free DWR, the Reserve Slim Insulated Jacket blends eco-friendly design with mountain-ready performance.
