Mammut Aenergy Tr Short - Men's

Product Insights & Style Tips

On the trail, the Mammut Aenergy Tr Short - Men's feels like a second skin: light, agile, and ready to move. The lightweight stretch fabric glides over climbs and descents, while breathable panels keep temperature in check as effort climbs. Reflective details catch the last light, and the soft interior minimizes friction for long sessions. Cut mid-thigh with a regular fit, this pair leans into a clean, sporty silhouette that suits hot-day miles and gradient miles alike. The fabric is 92% recycled polyester with 8% elastane, a nod to forward-thinking performance gear.

An adjustable waistband dial-ins the profile without pinching, and a single zippered waistband pocket stores essentials as you focus on terrain. The regular fit sits comfortably without bulk, while the mid-thigh length gives freedom to climb or stride out. Easy to layer over a lightweight tee or under a shell, these shorts move with you through transitions from warm-up to fast-paced sections.

Mammut's approach here leans on recycled materials and thoughtful details; reflective accents and a practical pocket set these apart in a lineup built for everyday training and steady progression. Pair with performance tees and trail-ready layers to build a cohesive, season-spanning kit.
