Ounce-counter special: The retooled Hightail has trapezoidal baffles to bolster insulation, a tough new shell, and a cut that’s less stingy at the shoulders than other featherweights. The 900-fill down compresses so well that even the bag’s modest stuffsack is too roomy. Only our coldest sleeper felt slightly chilled in 20 degrees at Mount Rainier National Park. 15°F, 1.9 lbs; www.thenorthface.com
Bonus: The vaulted footbox has a zipper vent for mild nights.
Bummer: The shell absorbed moisture when pressed against a soggy tent wall.
