STIO Fernos Insulated Pant - Men's Abyss, XL/Reg

The Fernos Insulated Pant pairs a synthetic insulated build with a full range of motion for cold-weather activity. Its PeakFill(R) Active insulation uses a spiral filament structure that recovers its loft faster and dries quicker than traditional insulation, so the pant regulates warmth instead of trapping it during effort. Articulated knees and an action gusset carry that mobility through the whole leg, and a jogger silhouette in a Regular Fit keeps the cut easy to layer under or wear on its own. What Our Gearhead(R) Experts Are Saying:"I've stood around at the trailhead in these without sweating through my base layer, then skied for an hour and never felt clammy. The insulation seems to know the difference between standing still and working hard."
