Cal 30 800-Fill DriDown Sleeping Bag: 30 Degree Down

Details

• 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
• Item #SDS0736
