From Backcountry
The Fernos Insulated Jacket is a synthetic midlayer built to regulate warmth as effort changes. Its PeakFill® Active insulation uses a spiral filament structure that recovers loft faster and dries quicker than traditional insulation, so the jacket adjusts to activity instead of overheating once the pace picks up. The Relance™ Primeflex shell adds mechanical stretch through the shoulders and arms, and a Regular Fit keeps the cut easy to layer under a shell or wear on its own. What Our Gearhead® Experts Are Saying:"I split wood in this on a fifteen-degree morning and never had to shed it, even once I was moving fast enough to work up a sweat. It just seems to let the heat out as I need it to."
