The Summit Line is our flagship performance sleeping bag series now better than ever that has been keeping backpackers warm since the start of OV. Cutting no corners we utilize top of the line materials and manufacturing best practices to provide the most warm & ultralight down sleeping bag for a better sleeping experience!
Technical products all start with the materials you put in them and the Summit bags have the best of the best. New ultralight ripstop fabrics by Toray™ improve consistency, give better hand feel, & reduce down leakage, while still adding durability. HyperDry™ 800 fill power hydrophobic down has been both certified and RDS sourced to make you feel like your sleeping in a warm cloud of comfort.
These materials are then carefully sewn into our upgraded baffle system to keep down from shifting while allowing for maximum loft. Our new differential cut will prevent down from getting compressed from the inside when you crawl inside your bag. This all adds up to more comfort for you, giving you more warmth and room.
Other updates include: increased depth & volume in the head area, dialed in baffle height for better loft, slightly more room throughout, an anatomically tapered footbox for more comfort, & an anti-snag ribbon behind the anti-snag YKK zipper!
What's more, a Roll-top Dry Bag & Storage Bag are included - giving you a better experience before, during, & after your trips!
The roll-top dry bag will help you both keep your sleeping bag dry AND compress it to fit more in your pack!
The storage bag will allow you to store your Summit long term without compressing the down - thus taking care of your sleeping bag & preserving its effectiveness.
The updates all contribute to high performance on all levels: warmth, weight, water resistance, stitch quality, & more. We didn't cut any corners, & did not focus on an end price goal while redesigning these sleeping bags. All that mattered is accomplishing the purposes of the sleeping bag even better than before!

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
- Use a mild detergent like Dreft (for babies) or Nikwax (for technical gear).
- Choose Low Spin or Delicate wash.
- Choose Cold Wash & Cold Rinse.
- Hang dry until the sleeping bag is completely dry.
- 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?
Basically 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!

I've wanted a center zip 30° bag for a long time. I'm a side sleeper and it seems nearly all sleeping bags place the side zipper on the wrong side for me. I was encouraged by positive reviews about this sleeping bag and saw that it went on sale, so I made the purchase. Overall the quality is top notch, the down lofts very well and there are no loose threads or construction issues at all. I do have two cons: the zipper system is a bit finicky on mine and the double zippers don't want to mate up properly at the bottom. It took me several minutes to get both zippers properly engaged. I wouldn't want to have to deal with that in the middle of the night. Also, I'm 6'5" tall and this bag seems just a bit short for me - when I stick my head in the hood my feet compress the insulation in the foot box. So it's not as long as I'd hoped to see in a "long" sleeping bag. Taking it out later this month for my first backpack and I hope it performs well.
I went backpacking last weekend and brought my new Summit 15 degree sleeping bag. The bag was comfortable and felt great. Probably the most comfortable bag I've ever owned. It got to around 30 degrees the first night and this bag, with an insulated sleeping pad, kept me warm. The bag is super light. I dropped about 2lbs from my previous bag which made carrying everything that much easier. I'm about 5'10" 220lbs and I bought the long. I made the right choice. The extra room at the bottom was good and the extra width made sleep didn't make me feel claustrophobic. It's an expensive bag but it's a pretty good deal when you consider the cost of other similar bags on the market. My friend spend over $100 more for a similar bag from another company. My only complaint, the zipper is hard to zip up when I'm in it. Once it's up, it stays up and sealed. It is easy to zip up and down when I'm out of it. Just wish the zipper was a little better.
Ordered the regular -15 bag, I'm 5-10 and my feet and head pushed against the bottom and top. Little snug at the shoulders also. Sent it back to try the long version that's 6" longer and 2 inches wider. Should do the trick.
I use this sleeping bag for my hunting and Boyscout outings. This is my 2nd one. I bought the quilt version for my son. Love it! Warm and easy to pack. It's all in the details! Love how they provide you with a storage stuff bag and compression bag! They do care about the user end. I recommend highly! Probably gonna get one now for my daughter. Thank you OV team!
