Product Details

The Aenergy FL Longsleeve is Mammut’s lightest, most technical base layer for year-round, multi-sport use. Made from 100% recycled polyester, the quick-dry fabric is designed to wick excess moisture from the skin for lasting dryness and comfort. Body-mapped mesh zones on the back and under arms enhance ventilation, helping to regulate body temperature. In response to peak levels of output, bio-based HeiQ Fresh FFL technology helps to reduce odours, maintaining a feeling of freshness. Cut with an athletic fit for optimum performance and easy layering, this technical long sleeve is primed to deliver.
