If you want a warm bag that is super light, look no further! The Dri Down Cal 13 is the lightest bag I have used that is rated for the cooler temps. This thing is like an oven when I sleep.


  • Light
  • Warm
  • Stuffable


  • None

I can't wait to use it on the PCT thru hike this summer! This thing also has great stuffability. I can cram this sleeping bag into the smallest of spaces.

I got this from SD and knew it was going to be a great product, just like everything else they sell!

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.


With game-changing hydrophobic DriDown(TM) insulation, the Sierra Designs Cal 13 sleeping bag is a go-anywhere, sleep-everywhere bag for weight conscious backpackers. 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 13 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.
