What Our Gearhead(R) Experts Are Saying:"I've used the Skyline Thermagraph Jacket on storm days and long tours, and it stands out for how warm it feels without overheating. The mapped insulation keeps the core cozy while the underarm vents dump heat quickly on the climb."From storm-day laps to backcountry pushes, the GORE-TEX Skyline Thermagraph Jacket keeps us warm, dry, and moving freely. Built with a recycled 2-layer GORE-TEX shell, it delivers waterproof, breathable protection that seals out blizzard conditions while allowing airflow during high-output ascents. The Thermagraph(R) Active insulation system strategically maps warmth with lightweight graphene fleece, so we get targeted comfort without unnecessary bulk. Every feature is tuned for mountain use: helmet-compatible hood, powder skirt with stretch panel, and fully taped seams to block out snow. Zippered underarm vents open wide for quick heat release, while welded cuffs, adjustable hems, and glove-compatible wrist gaiters keep warmth locked in. With eight total pockets-including phone, pass, and goggle storage-it carries mountain essentials securely through big days in the backcountry and long sessions at the resort.
