The Ortovox Ortler Softshell Plus Jacket blends merino wool into an elastic softshell body fabric that breathes easily against the skin during a long climb. WINDSTOPPER paneling covers the torso specifically, shielding the core from wind while underarm vents stay open for airflow during exertion. A helmet-compatible storm hood pulls on quickly when wind or snow moves in, and backpack-compatible front pockets stay accessible with a hip belt cinched down. What Our Gearhead® Experts Are Saying:"I pull the hood over my helmet the second the wind kicks up on a ridge, then vent the underarms back open once I'm moving again on the climb. That quick a switch is what keeps me from stopping to dig out another layer."
