The North Face Casaval LT Vest is engineered for mountain athletes who demand precision performance during high-output activities like climbing, alpinism, and technical backpacking. This minimalist layering piece features revolutionary VENTRIX™ laser-perforated insulation that actively regulates your temperature, breathing with your body to prevent overheating on strenuous ascents while maintaining core warmth when you pause to belay or navigate. The strategic non-insulated side panels provide unrestricted arm movement for technical maneuvers, while FLASHDRY™ moisture management keeps you dry from the inside out. At just 25g of recycled synthetic insulation, this vest delivers the perfect balance of warmth and weight savings that serious mountaineers require, making it an essential piece for any alpine layering system where every gram counts and temperature regulation can make or break your summit bid.
