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. From weekend explorations to weeklong expeditions, Atmos AG LT 50 is up to task.

Made with bluesign® approved, recycled main body fabrics and designed to pass the test of time, no matter where you take it.

We offer FREE delivery on all orders over €100 (excluding overweight items*) to the Republic of Ireland and Northern Ireland. For any order below this value, we charge a small delivery fee of €5 per delivery. Exceptions apply. Read more here.
