Osprey Exos Backpack
Best ultralight pack for experienced hikers tackling multiday adventures.
This is the gold standard for thru-hikers who refuse to sacrifice comfort for a lighter load. The suspension system creates a literal breeze against your back, though you’ll have to be disciplined with your packing since the ultralight frame isn't built to haul heavy, unnecessary gear.
$265.00
