Comparisons
Mystery Ranch Glacier 70 vs Gregory Baltoro 75
The Gregory Baltoro 75 offers better internal organization and is slightly more comfortable for heavy hauls, but the Mystery Ranch Glacier 70 takes the lead in durability and external access. It’s a better choice for rugged environments and bushwhacking where gear takes a beating.
Mystery Ranch Glacier 70 vs Osprey Atmos AG 65
The Osprey Atmos AG 65 is significantly lighter and more breathable, but it can’t match the Mystery Ranch Glacier 70’s load-carrying capability or durability. If you’re going off-grid with lots of gear, the Glacier is built for the job.
