Less is more with the Atmos AG LT 50, delivering our extraordinary, ventilated and comfortable AntiGravity suspension in a more streamlined silhouette for technical backpackers. Even lighter than its original counterpart, LT delivers the same best-in-class carry while providing a thoughtfully simple, capable feature set, including an integrated raincover, side panel zip access, floating top lid, reinforced shove-it pocket and internal hydration sleeve.
