Built For Real Conditions

The Summit uses hydrophobic-treated down and a DWR-coated shell to improve moisture resistance. This helps the insulation maintain loft and warmth better than untreated down.

While not waterproof, it performs reliably in typical backcountry humidity and condensation.

Product Care

Your Summit Down Sleeping Bag is a high performance piece of gear. It needs some extra attention to keep it performing at the highest level.

Please read through the care instructions below to ensure that you care for it properly:

Before Washing

  • Always wash your down product completely alone to prevent down migration.
  • Never wash your down product in a washing machine that has an agitator.
  • If you cannot follow either of these prior instructions you should hand wash your sleeping bag using the detergent and drying process described below.


The Wash & Dry Process

  1. Use a mild detergent like Dreft (for babies) or Nikwax (for technical gear).
  2. Choose Low Spin or Delicate wash.
  3. Choose Cold Wash & Cold Rinse.
  4. Hang dry until the sleeping bag is completely dry.
  5. Then loft and redistribute your down insulation in the dryer by running it for 10 minutes on low or no heat with 3 dryer balls.


Long Term Storage

  • Do not store down product compressed long term. Long term compression weakens the insulation's ability to loft and therefore insulate.
  • We recommend hanging it in your closet or putting it in a pillow case for storage between uses.​
