Aenergy Light Tights

Built for fast-and-light mountain objectives, these bottoms bridge the divide where traditional hiking pants feel excessively heavy and standard running tights shred against bare rock. The dense polyamide and spandex blend delivers a supportive, skin-tight fit with generous four-way stretch, shedding excess heat efficiently on steep technical ascents while maintaining enough tensile strength to shrug off casual scuffs against rough granite.

In the field, thermal regulation is the primary asset. The fabric moves moisture outward immediately during high-output efforts, drying quickly after exposed ridge gusts or river crossings. Mammut dialed in the functional details for alpine travel: the flat, drawcord-adjustable waistband rests comfortably beneath a heavy backpack hipbelt or climbing harness without pinching, and the streamlined pockets remain reachable even when tied into gear loops.

While substantially more abrasion-resistant than standard Lycra leggings, they lack the windproofing and snag resistance of full-weight woven softshell trousers. They will not protect against jagged scree slides or dense off-trail brush, and their thermal envelope is strictly limited to warm conditions or high-heart-rate cool days. Still, for runners and scramblers prioritizing unrestricted leg articulation and rapid moisture transfer over heavy-duty protection, they offer a dialed, distraction-free solution.
