Most Breathable
Seems like 2,000 cubic inches is the magic number when it comes to versatility—just big enough to max out on a fast-and-light overnighter but not too big for a day hike. And size isn’t the only thing the top-loading Spectro AC gets right. It was the most breathable pack in our test. The lightweight steel frame and mesh-backed ventilation system struck the right balance between airflow and load carrying. “It was stable when fully loaded,” said one tester, “but it rode light on quick, hot hikes, too.” Our favorite feature? A large, U-shaped front zip that allows you quick access to gear jammed down in the bottom of the pack. 2.6 lbs;
