Summary
Extra-cushioned hip belt, shoulder harness, and back panel make the Baltoro 75 (men's) and Deva 70 (women's) the most comfortable option for carrying 40-50 lb loads on week-long trips. The ultraplush lumbar pad molds to your back and prevents hip belt drift.
The suspended mesh back panel wraps onto the hip belt for unmatched comfort on multi-day trips. Lighter than the standard Atmos AG while keeping all the features that make Osprey the trail standard.

- At 4.2 lbs, heavier than ultralight options like the Granite Gear Blaze or Hyperlite Southwest
- Premium price tag around $320
- Less feature-rich than the standard Atmos AG 65 (fewer pockets, less adjustability)
Our take
If you're going out for 7+ days or carrying winter/climbing gear, the Baltoro/Deva is the pack. Yes, it's heavy — but when you're hauling 45 lbs, the extra cushioning pays for itself in spinal health.
If you only buy one backpacking pack, this is it. The Anti-Gravity suspension is genuinely different from everything else — testers describe it as a 'hug,' and after miles on trail, that's not hyperbole.
