Gregory Deva 60 ($370): A Near-Carbon Copy Like the Ariel, the Gregory Deva 60 (men's Baltoro) is a heavy backpacking pack for heavy loads

How we tested We evaluated each pack across real European travel scenarios: Gate sizer fit Passed through metal sizers at Dublin, Stansted, Bergamo, and Barcelona on Ryanair and easyJet flights Urban comfort Walked 15+ km days in Paris, Rome, and Lisbon with each bag fully loaded Packing efficiency Fitted two weeks of clothing, toiletries, laptop, and chargers using packing cubes Durability Checked zippers, fabric abrasion, and harness condition after 6+ months of use Access speed Timed laptop removal at security and accessibility of passport pocket Weight distribution and hip belt support mattered most on cobblestone streets

Size is Accurate I have a 17.25 inch torso so I went with the S/M size per the Tempests official sizing for S/M (17-20)

I have been silently using this backpack for years
