A mild- to cold-weather down sleeping bag that isn't afraid of a little moisture.
As the campfire begins to fade, slip into your tent and slide into the Sierra Designs Cal 30 800-Fill DriDown 30 Degree Down Sleeping Bag. DriDown insulation retains its warmth and loft even if it gets a bit humid or dewy during your late-fall camping trips or early-spring climbing excursions.
- With an EN comfort rating of 39°F and a lower limit of 30°F, this bag is best suited for cold late-fall or early-spring nights where temperatures rarely dip below freezing
- EN ratings are developed from procedures and testing conducted by independent organizations in the US and Europe
- 800 fill-power goose DriDown insulation features a hydrophobic finish that enables the treated down to stay drier, loft better, and dry faster compared to untreated down so you're able to stay warmer for longer in any situation
- Insotect Flow construction features vertical down-filled baffles that help facilitate heat distribution more readily from head to toe than traditional side horizontal channels
- Vertical channels also efficiently mirror the contours of your body, lessen down shifting, and reduce overall construction materials
- FlowGate technology holds insulation in place for reliable warmth and comfort
- Mummy-shaped bag decreases weight, cold spots, and packed size
- A 10D ripstop nylon shell offers lightweight performance while a DWR coating supplies protection against early-morning frost
- Ultralight jacket hood, ergonomically-shaped footbox, and zipper draft tube insulate your body and prevent the cold from seeping in
- Thermally-efficient 40-inch snag-free zipper offers an easy in-and-out
- Collar drawcord with captured cordlock lets you cinch the collar down around your face for a snug fit
- Includes storage and stuff sack

Super light, warm bag
- Familiarity: I've used it several times
Dew dried quickly on this bag over two one-week long adventures. Lofty and warm all week. Crazy light. Warmer than expected for a 30 degree bag and comfortable at 40 with a bag liner and no clothes.
Zipper seemed like a 1/3 zip bag (even if it is actually closer to 1/2 zip), which is the primary drawback for me. In 50+ weather, you can't unzip completely to use the bag as a blanket or fully vent so you are left a bit too hot. Fairly narrow lower leg section, which might constrict some side sleepers. Zipper catches often but that is not unexpected in the ultralight world of bags. I would trade a couple ounces for a full zip and the associated versatility and rate this bag 5 stars.
- Familiarity: I've used it once or twice and have initial impressions
So far, two 40 degree nights and the bag was plenty warm and comfortable. Haven't had to test the water resistance response of the down, but after testing multiple bags, I am very happy with this choice in the field.
