Deceptively simple, decidedly bombproof, this parka provides a high degree of alpine protection while keeping weight at an absolute minimum. Fully seam-taped 15D Gore-Tex® PacLite® fabric and water-resistant zippers make the Celestial seriously stormworthy. TorsoFlo^TM side zips perform well with a pack on, allowing optimum venting during strenuous activity. Weighing around half a pound, this jacket lets you go faster and lighter without sacrificing protection.
