Why We Like The Mammut Aenergy Light Softshell Pant

The cool temperatures of alpine elevations and seasonal switches call for added coverage, provided by the Mammut Aenergy Light Softshell Pant. The low-weight double-weave softshell fabric offers abrasion resistance ideal for hiking through brush and close encounters with rock face. Quick-drying, water-repellent, and breathable properties keep us comfortable as we pick up the pace, and an adjustable fit offered by the elasticated waist keeps a snug profile ideal for mountain movement.

Performed well in tough environment

I wore these pants while hiking in the Catskills in a full out winter storm... cold temperatures, high winds, and tons of snow! With a pair of long underwear, these pants kept me warm and dry throughout the day. They are comfortable to hike in and great to glissade in! They are so versatile, that I plan to add them to my pack on hikes in Virginia, New England, and in Rocky Mountain National Park this summer.

Way too tight!

Like all clothing from Mammut I have found they fit way to small. I'm a consistent size 36, but Mammut size 36 is like a 32.
