Cold Days 2nd Layer Vest - Men's

What Our Gearhead® Experts Are Saying:

"The Cold Days 2nd Layer Vest is the piece I reach for when conditions are cold enough to need more than a base layer at the core but not cold enough to justify full sleeve insulation. The Polartec Alpha construction delivers genuine warmth at 128 grams, and the sleeveless cut keeps the arms unrestricted through the full pedal stroke. It integrates cleanly with any Castelli base layer and jacket combination and gives riders a meaningful step between their warmest base layer and their coldest full jacket."

Where the Cold Days 2nd Baselayer addresses the most extreme end of the cold weather spectrum, the Cold Days 2nd Layer Vest from Castelli targets the broader 24 to 50 degree Fahrenheit range with a sleeveless construction that concentrates Polartec Alpha insulation at the core without adding coverage the arms do not need. The result is a more ventilated mid-layer that keeps the chest and back warm while preserving full arm mobility and airflow through harder efforts.

At 128 grams, the vest adds negligible bulk under a jacket and shifts the entire layering system's warmth profile upward without changing its fit or feel at the shoulders or sleeves. For riders who run warm in the arms but need core protection on cold and windy days, the vest configuration solves that problem more precisely than any sleeved alternative. Paired with a quality base layer underneath and a Castelli winter jacket on top, the Cold Days 2nd Layer Vest gives riders a highly adjustable system that works across a wide range of winter conditions.
