On the days you can hear the wind before you even step outside, you'll need more than just thermal insulation to keep you warm as you ride. De Marchi created its classic Leggero WP Jacket for days like that, arming it with an outer Windtex membrane to block out chilling wind. This shell is bonded to insulating layers of nylon and brushed polyester that retain heat by creating a warm microclimate between your skin and the biting air. We've moved on from the days of puffy, billowing windbreakers, and the Leggero's fit is tailored to sit close to the body. This fit is complemented with a touch of elastane in the jacket's fabric to keep it moving with you as you change positions on the bike or reach into the three rear pockets. De Marchi states that the Leggero is best suited to the mid 50s, but with the right base layer, we'd wear it into the low 40's without a second thought.
