For cold weather backcountry overnights, the ultralight Cal 6 has you covered. Featuring patented InsoTect Flow baffles insulated with DriDown hydrophobic down insulation and 10D nylon ripstop shell and liner, the Cal 6 is feathery-light, warm, and compressible, offering outstanding performance in damp, humid, snowy environments.


  • Patented vertical baffle construction
  • Ergonomically shaped footbox
  • Ultralight Jacket Hood
  • Thermally efficient 40 in. zipper
  • Snag-free zipper tracks
  • Zipper draft tube
  • Full, corded, draft collar

Simply put, DriDown represents the evolution of down insulation. Regular down is treated with a molecular level polymer to create a hydrophobic finish on each individual down plume. This finish allows DriDown to stay dry longer, loft better, and dry faster than untreated down, keeping you warmer in any environment.
  • Stays Drier: Stays dry 10 times longer than untreated down.
  • Keeps Warmer: Retains 170% / 2.7 times more loft than untreated down when exposed to moisture and humidity.
  • Dries 33% faster than untreated down.
