THE SELL: Ultralight goes mainstream. THE TEST: At well under three pounds, the 48-liter Fluid is remarkably svelte for a tweener daypack-overnighter. We loved the flexy feeling in the harness and the slew of innovative perks, like sleeping-pad straps that stow away and an externally accessed hydration bladder. THE VERDICT: This is the rare pack that will appeal to ultralight folks, gram-counting overnighters, and the bring-the-sink day-hiking crew. But not the heavy sink—the Fluid started to buckle at 40 pounds. 2.7 lbs
Hauling comfort: 40 pounds
