On a two-day hut trek in New Hampshire’s Presidential Range in June sunshine and high humidity, a friend and I hiked 21 miles with about 6,000 cumulative feet of elevation gain and loss each day, including scrambling up the steep slabs and talus of what’s widely recognized as the hardest trail in the White Mountains: Huntington Ravine, and descending some little-used trails in steep terrain and clambering over the broad, rock-strewn bed of the Dry River. Through the countless high-stepping and four-points-of-contact movement and the hours of streaming with sweat, the Deuter AC Lite 23 demonstrated its strengths of comfort and back-cooling ventilation.
