"What Our Gearhead® Experts Are Saying:""I use the MTN-X Horn 3L Pants on deep storm days and warm spring laps alike. The Dermizax fabric keeps me dry through everything, and the stretch gives them a more natural fit for touring. Outseam vents dump heat fast when I’m climbing, and the boot connector system seals the deal for big-mountain days.""From midwinter powder missions to sun-soaked spring corn laps, the MTN-X Horn 3L Pants are our daily driver for the backcountry. Built with 3-layer Dermizax® shell fabric, these pants deliver reliable 20K/20K waterproof breathability with mechanical stretch that moves easily through skin tracks, bootpacks, and booters alike. Fully seam-sealed and dialed with mountain-specific details, they're ready for every ascent and descent on the calendar. Venting is managed with long outseam zips for quick dumps of excess heat, while articulated knees and a stretch waistband let us move freely over technical terrain. A zipped hand pocket and cargo pocket keep essentials close, while reinforced cuffs and integrated gaiters seal out snow. Built for days when performance and protection matter most, the Horn 3L Pants don’t flinch when conditions turn burly."
