Mammut Aenergy Light ML Hooded miesten fleece-takki Silver Sage-Strata

For alpine athletes who refuse to let a midlayer slow them down, the Aenergy Light ML Hooded redefines what a technical fleece can be. Its Pontetorto Tecnostretch fabric offers a rare combination of four-way stretch, high breathability, and featherlight warmth, making it the go-to layer for ski touring, mountaineering, and fast-paced ascents. At just 280 g (size L), it packs down small yet delivers reliable insulation when the wind picks up.

In daily use

Designed for the vertical world, the Aenergy Light ML Hooded excels as a midlayer during ski touring and mountaineering. Its high breathability ensures you won’t overheat on the ascent, while the stretch fabric moves freely with your body. The close-fitting hood adds extra warmth without interfering with a helmet, and the strategically placed pockets remain accessible even when wearing a climbing harness or backpack. The thumb loops offer a secure fit and prevent the sleeves from riding up.
