Product details

Part of Sea to Summit’s Spark™ Ultralight Mummy Sleeping Bag Series, the Sp II provides warmth down to around 35 degrees Fahrenheit and weighs just over a pound, making it ideal for backpacking, bike touring, and alpine adventures from late spring to early fall. It’s made with high-loft, responsibly sourced, 850-fill goose down for warmth with minimal weight, and treated with Ultra-Dry Down™ water repellent to fend off moisture. Key Features:

  • 850-Fill-Power Down – The insulation is made of high-loft, premium European goose down that meets the Responsible Down Standard (RDS), which safeguards the welfare of the animals that provide the down and feathers. - Ultra-Dry Down – A water-repellent polymer treatment is applied to the down, which retains 60% more loft and absorbs 30% less moisture than untreated down.
  • Lightweight Nylon Shell + Liner – The 10-denier shell is incredibly lightweight, compressible, and windproof, and the 7-denier liner provides soft, next-to-skin comfort.
  • Mummy Shape – The contoured mummy shape creates a snug fit with enough room for movement and thermal efficiency. - ⅓-Length Zipper – The ⅓-length zipper weighs less than a full-length zipper.

Made with Sea to Summit's special downtek down which keeps your bag 90% more dry than untreated down. Also dries out super fast in the sun :)
