Product Care

Your Aerie 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.​

The Aerie is THE best, not only underquilt but sleeping bag. The customer service is good. The bag itself is super warm and will get the job done.

Really nice bag!

Purchased the 0* bag and really like the fact it is spacious, square bottom and the very bottom unzips so my feet can stick out. It is one of the main things i dislike about most bags is the inability to unzip the bottom. Haven't used it in the cold yet.

Couldn't sleep the night through in my hammock as my back always got too cold. I have slept through every night since I purchased this! Definitely worth it! And it's warm warm warm!!

Love this thing

I have a few under quilts. This is the second OV Aerie quilt that I purchased. The first once was a 15° Loft Tek quilt and this one is a 0° down quilt. I needed a second under quilt for friends and for colder weather. Quilt arrived quickly and looks great. I have already added my shock cord and carabiners hack (to the loops on each end of the bag) that make using it as an under quilt better. I recommend adding these to your bags as they allow the ends to gather around you hammocks. This makes it so that you do not have to worry about shifting the under quilt around as you sleep since it stays in place and does not drop below the hammock while allowing the ends to flex as needed to accommodate movement.

Best sleeping bag!!!

It is light. Warm, and rectangular. I love it because it is rectangular. I can move my feet and legs freely. I introduced it to my friends and several of them bought it.
