M’s Thermalrunner Hybrid Insulated Jogger

The Thermalrunner Hybrid Insulated Jogger is our extreme cold-weather jogger, with targeted insulation panels and a full-leg stretch gusset for a fit that feels like a cross between a legging and a pant. It has a tapered jogger fit, an elastic waistband, and fleece-lined hand pockets for when your fingers need a break from the cold.

There’s ultralight (25gsm) insulation where you feel cold the most, across the front and seat, so you get the warmth you need without the weight or the overheating. The outside of each panel is a smooth, water-resistant stretch nylon that doesn’t have a distracting swish with every step, and the inside is a soft mesh fleece. Wear it on its own, or pull it over a tight or short when the temperature really drops. Targeted panels of our Atlas fabric add serious durability and plenty of room to move.
