When the journey calls for a lightweight pack but you can't afford to compromise on comfort and carry capacity, the streamlined Atmos AG LT 65 proves it's possible to optimise for both. From weekends flush with gear to your longest backcountry expeditions, LT delivers the same body-hugging AntiGravity suspension while providing a thoughtful, streamlined, capable feature set. Trimmed weight where it counts while considering the core features that make Atmos so versatile: an integrated raincover, side panel zip access, floating top lid, reinforced shove-it pocket and internal hydration sleeve. Made with bluesign-approved, recycled main body fabrics and designed to pass the test of time, no matter where you take it.
