Like dinner with the in-laws, running with a backpack can get awkward at times. Enter the Lobex Lumbar Pack from Columbia Sportswear: a light-and-fast waist pack with the featherweight yet supportive Mobex-rod-frame construction. Its built for moving quickly and carrying the bare minimumthink marathon training or daring trail ascents. Mesh internal gear organizers keep all your cargo secure and accommodate up to a 50-ounce hydration bladder. The fully wrapping hip belt and padded back are breathable and supremely comfortable. In fact, we have it on good authority from our testing team that after the first mile in the Lobex, you forget its even there.
