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.​

HyperDry™ Down

What is HyperDry™ Down insulation?

It's high-performing down that has been DWR treated on a down level for increased water resistance.

If down gets wet, it collapses (loses its loft) & no longer insulates. That's why we use HyperDry™ Down in the Summit Sleeping Bags!

This means you get all the weight & compression benefits of down (that's still what it is) PLUS you get a bit more protection from moisture than standard untreated down.


Differential Cut

What is a differential cut?

It means that the inside fabric is cut smaller than the outside fabric.

When you are inside a sleeping bag, you tend to move around a bit & press up against the inner fabric. A differential cut ensures that you don't compress the insulation inside the sleeping bag, even if your knee, elbow, etc. presses right up against the inner fabric!

This means you get a warmer sleeping bag without cold spots!

Worth it!

Undoubtedly the most comfiest sleeping bag I have ever owned. Though I bought it for all year round, it's easy to sleep on it during the summer. I am looking forward to sleep in it when it is cold.

Thomas Koehn
Great Product!

Picked up the summit 0 degree sleeping bag I have No complaints, Super warm and lightweight! I would recommend to anyone!

Rodney Hale
My second Summit bag.

I bought my first Summit bag (20 degree) in 2018 and it never let me down in some really cold conditions; I pair it with either hammock/under quilt or the OV insulated pad. I had to use it as a quilt most of the time as it was that warm. What I loved the most was the foot box which was loaded with extra down. My feet not even once got cold and most of the time I had to shed my socks. Unfortunately it does not appear as if OV carried that feature over to the new edition. I used my new 15 degree bag just last night when it got really cold, low 20s or so, and I was shocked to be woken up with frozen feet as I was wearing a thick pair of wool socks. I am impressed with everything else about this new bag but very disappointed with the footbox. I will have to buy a pair of the down footies now to avoid this predicament in the future.

Great 1st Impression

I purchased to thru hike the AT during the cold temperatures of January, February and March. The bag performance was awesome and I had to peel sleeping layers off to keep from overheating. I had temps in the twenties with sleet and freezing rain. Definitely builds up confidence to embrace the cold suck! Note worthy to add the ordering process and delivery was excellent! Thank you!

Warm and cozy

I tested out my zero degree bag this past weekend. It got down to 29 and i was plenty warm. I was in a tent with a thermorest pad. I wore heat gear bottoms and a ventice hoody. I ask ov for their thoughts on the sizing. After opening it up and letting the bag fluff up tried it out. At first it looked too small but once zipped up inside it was a nice cocoon of fluffy feathers. I'm glad I didn't size up this bag is perfect.
