La Sportiva Koro Jacket - Women's Cypress/Night Sky, L

The La Sportiva Koro Jacket is a hybrid insulated running jacket that pairs PrimaLoft ThermoPlume insulation across the front with stretch fabric on the back. The insulated front holds warmth where the wind hits, while the back stays free to move and release heat. That split suits winter trail running and ski mountaineering, where effort stays high and conditions shift. What Our Gearhead(R) Experts Are Saying:"I unsnap the chest flap on a steady climb, and the heat that builds under the insulated front vents out through the opening. When the pace drops or the wind picks up, I snap it shut, and the front holds its warmth through the descent."
