Say goodbye to midwinter chills. Relance™ Primeflex and PeakFill™ Active Insulation combine in this fully articulated, warm and highly breathable active insulation midlayer.

Stand up to the most daunting weather reports and midwinter chills with our Fernos Insulated Pant. This reliably warm and highly breathable insulation midlayer laughs off sub zero days with a Relance™ Primeflex shell and PeakFill™ Active Insulation. The medium cut is designed for an on-the-go lifestyle, be it a pick-up pond hockey game or chasing the kids up the trail. Stretch panels and full articulation allow for complete freedom of movement while thoughtful design details like an encased elastic waistband, zip fly and drawcord make for easy on and off—although the Fernos is the type of insulated comfort you won't want to shed anytime soon.
