What Our Gearhead(R) Experts Are Saying: "This is my favorite alpine pack for fast missions and summit pushes. It's crazy light, fits close to the body, and doesn't get in the way when I'm climbing. It carries surprisingly well for such a minimalist build, and the Cordura fabric is tough as nails."Built for elite alpinists and fast-moving climbers, the Mammut Trion Nordwand 15L Backpack delivers ultralight functionality without skimping on durability. Developed with input from Mammut's pro athletes, it's designed for summit pushes, minimalist alpine routes, and steep objectives where every ounce and every move matters. The featherlight Cordura ripstop fabric resists abrasion, while the close-fitting design stays stable while climbing, scrambling, or moving fast through mixed terrain. Simple yet refined, it includes essential features like an internal gear loop, hydration compatibility, and a secure rope attachment strap-everything we need, nothing we don't.
