Helly Hansen LifaLoft™ Full Zip Insulator Pants - Women's

First conceived as a way for Helly Hansen's freeriders to stay warm before dropping in, the Helly Hansen LifaLoft™ Full Zip Insulator Pants are like vests for your legs: they're easy to take on and off, they're warm as heck, and they won't interfere with your movements should you decide to leave them on. Whether under your shell pants or chilling after a long day on the hill, these are money.
