"What Our Gearhead® Experts Are Saying: ""Once I tried the Puffer Pant, I stopped wearing regular baselayers on cold days. The insulation in the thighs is a game changer on chairlifts, and the fleece everywhere else keeps things breathable and mobile. I even wear them as joggers off the hill—they're that comfy."" Designed to solve the problem we didn’t know we had, the Flylow Puffer Pant delivers cozy, insulated warmth right where we need it most—on the chairlift and in the coldest conditions. Combining stretchy gridded Furano Fleece with 40g of Primaloft Black ECO insulation above the knees and across the upper thighs, this baselayer hybrid keeps our core temps high without sacrificing breathability or mobility. The Pertex® Quantum shell fabric blocks wind and boosts thermal efficiency, making these the perfect foundation for layering under shell pants or bibs on freezing days. When the ski boots come off, we wear the Puffer Pant like our favorite pair of cozy joggers—whether lounging at home or grabbing coffee after a few laps. From storm-day layering to everyday comfort, these are a cold-weather essential."
