Down-insulated, harness-compatible shorts that make gusty, freezing belays bearable. The 20D Pertex® Quantum Pro fabric with Pertex Diamond Fuse technology features a microporous coating for a high level of water and abrasion resistance. The seat area features G-LOFT® EVOX fabric for added durability and moisture-management. The 900-cuin-fill-power DRY DOWN traps warmth, even when wet. Ideal for wearing over shell pants, these shorts combine lightweight warmth with durability. Full side zips provide easy-on-and-off. Designed in collaboration with alpinist Marek Holecek, the Eiger Nordwand Light Down IN Shorts are ready for every north-facing ascent.
