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掳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.
