  • Lofty 850-fill-power goose down provides excellent insulation and compresses down small when you're packing the bag away
  • Buttery-soft, featherweight nylon ripstop fabric has a Durable Water Repellent coating to help keep moisture from seeping in to the down
  • Use the optional lacing system to close the back of the Siren to retain warmth on especially chilly nights; snap at the collar keeps you tucked in
  • Stretch stitching helps maintain bag shape and down loft while also allowing the bag to subtly move with you throughout the night
  • Blanket Fold™ insulated flap of fabric can be wrapped around your neck to block drafts and add warmth
  • When the Siren is paired with a regular or short NEMO Zor™ sleeping pad (sold separately), your total sleep system weighs in at 2 lbs. or less
  • Insert your sleeping pad inside the Siren, or lay on top of it; Siren accommodates a variety of pad widths
  • NEMO Siren 30 down sleeping quilt comes with a roll-top compression stuff sack and a storage bag
