A sleek fitting and very breathable vest that fits under even snug shells with ease, the Mammut Aenergy IN Vest heats your core with 95 g/m² of Polartec® Alpha® Direct lining-free synthetic insulation for minimal bulk. The shell is a combination of Pertex® Quantum Air in high wear areas and a stretchy wicking Poly-Elastane knit elsewhere. While we don't claim it will give you wings like some of those aenergy drinks, this vest will help keep you out on the hill when the going gets chilly.
Front and Shoulders – 100% Polyamide Pertex® Quantum Air
Back and Hips – 96% Polyester / 4% Elastane Knit
100% Polyester Polartec® Alpha® Direct | 95g – Polartec® Alpha® Direct is an evolution of original Alpha® technology that eliminates the need for a backing fabric to create an enclosed fabric package. By refining the shape and size of its lofted fibers, Alpha® Direct can be in direct contact with skin or other fabric layers. This new design ability increases breathable performance, expands versatile style options, and further reduces overall garment weight.
