I've always been a big fan of the MHW softshells but their offwidth jackets are cut way to short in the torso. Decided to try the Marmot Altitude and have been thoroughly pleased with quality and fit. A much normal length. Also the jacket does have a light fleece type insulation in the enter lining.
Marmot M-series fabrics are designed for moving light and fast. They combine stretchable, water repellent, abrasion resistant and highly breathable shell materials with insulating buffer materials on the inside.
M2 shells are the ideal balance between weather resistance, breathability and thermal protection. They are appropriate for a wide range of aerobic use in moderate to cold conditions.
