Pack Light

ADVANCES IN SOLAR PANELS in recent years have led to some promising developments in off-the-grid recharging, with light, flexible cells that can be fused into tents, backpacks, and even clothing. Alas, the designs have thus far placed utility above style—executed with all the flair of a Soviet architect. But this fall, a handful of startup bag companies have finally gotten it right, releasing several slick haulers that harness daylight to recharge internal batteries or feed power directly into electronic devices (though not laptops—yet) through regular cigarette-lighter adapters. Similar refinements in tents and jackets are expected to hit the market next year, but these four daypacks have already claimed their place in the sun.
