Details

  • Down is widely considered the best insulation available, but when wet it quickly loses loft and the ability to keep you warm; DriDown is treated to resist moisture
  • Proprietary process treats each individual goose down plume with a molecular-level polymer so the down stays dry longer, lofts better and dries faster than untreated down
  • DriDown insulation stays dry 10 times longer, retains 170% more loft when exposed to moisture and dries 33% faster than untreated down
  • Vertical baffles keep the down in place so you stay warm even if you move around a lot at night
  • 40 in. zipper keeps weight down and won't let out all the warmth when you're getting in and out of the sleeping bag; locking slider is backed by wide, antisnag binding tape
  • Snag-free zipper tracks prevent the dreaded stuck zipper by creating a barrier between the lining and the zipper track
  • Fully insulated draft tube backing the zipper keeps body heat in and cold air out
  • Ergonomic, nonrestrictive hood cradles your head in warmth; use the drawcord at the collar to cinch the hood snug around your head
  • Sierra Designs Cal 30 sleeping bag comes with stuff sack and storage bag
  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
