Phantom Mountain Jacket – Men's

Built for fast-and-light mountain running and alpine scrambles where weather moves fast, the Phantom Mountain Jacket is our pick for athletes who need real waterproof protection without the weight. Seven-denier Pertex Shield 2.5-layer stretch fabric keeps you dry and moving freely on steep, sweaty ascents. It packs into its own micro stuff sack — small enough to forget it's in your vest until you need it.

• 7D Pertex Shield 2.5-layer stretch fabric delivers full waterproof and windproof protection at a fraction of standard hardshell weight
• High breathability rating handles sustained uphill effort — critical for trail running and fast hiking in humid Southern summers
• Low-volume hood with stiffened peak and YKK front zip with storm flap seal out wind and rain without restricting vision or movement
• Pre-shaped articulated sleeves and partial elasticated cuffs and hem move with you on scrambles, trekking pole work, and technical terrain
• Packs into an included micro stuff sack — fits easily in a running vest or daypack as a dedicated emergency storm layer
