"What Our Gearhead® Experts Are Saying:""I grab this vest for high-output hikes when I want core warmth without overheating. The Pertex Quantum Air fabric breathes really well on climbs, and the AirMesh lining adds just enough insulation to take the edge off cool mornings. The pocket layout is super functional for snacks and a phone on the move.""For brisk trail starts and long days on the move, we rely on the Kor Airshell Warm Vest from Mountain Hardwear to strike the right balance between warmth and airflow. Lightweight and technical, it keeps our core insulated without restricting movement or trapping excess heat. The Pertex Quantum Air stretch ripstop fabric offers breathable weather resistance and durability for rugged terrain, while the AirMesh lining delivers subtle warmth with impressive ventilation. A full-length zipper makes layering simple, whether we’re pairing it with a base layer or sliding it under a shell. Two zippered hand pockets and two zippered chest pockets keep essentials secure and accessible, making this vest a versatile companion for hiking and camping adventures."
