The new Cal Series from Sierra Designs utilizes Dri Down technology as well as Insotect baffle construction. The Dri Down keeps you warm and dry, even if your sleeping bag isn't so dry. The Insotect Flow's vertical baffles or vertical thermal channels (VTC's) distribute heat more readily from head to toe compared to traditional side-to-side horizontal baffle. This bag has what it takes to keep you comfortable, and is light enough for your excursions in the backcountry.


  • Patented vertical baffle construction
  • Ergonomically shaped footbox
  • Ultralight Jacket Hood
  • Thermally efficient 40 in / 102 cm zipper
  • Snag-free zipper tracks
  • Zipper draft tube
  • Draw cord at collar with captured cordlock
  • Includes stuff and storage sacks

    Comments about Cal 30 Sleeping Bag (800 Down):

    Its always a bit of a gamble between going lightweight and getting something that is actually worthwhile and suits its purpose. This bag just sneaks in for that. Its a fine line between going lightweight and keeping warm at that near below freezing level, and spending several nights at about 35 in the rockies, i found myself comfortable, rather than warm at this level, however, this was essentially sleeping nude, so add a layer of thermals to that, and cosy would be the word. It is very light, and certainly when you look through the bag with backlight, you worry about all those clear patches through the down, but it performed well, with very good loft. The hood is fantastic, i love a good warm hood and it excels there, with very good room in side the bag and adequate room. This bag is perfect for what i wanted, african travel, summer hiking where it could touch freezing, and in new zealand, winter hiking in huts. Yes, its not super warm when the temp drops, but there is a sacrifice for weight and bulk and i think they have hit the mark here on that fine line between weight and actual usefulness.
