Lightweight, warm, compact and comfortable! It’s like a bag and quilt all in one. I need a warm toebox and love the fact that I can keep my feet nice and cozy while draping the rest over my upper body. This allows me to move around very easily and adjust. So far I love the bag!

When the temperatures drop, stay warm and cozy with our award-winning Classic Sleeping Bag. Striking the perfect balance of warmth and weight,​ our ultralight Classic Sleeping Bag features a 3/4th length zipper on the bottom, combining the best aspects of a down quilt and a down sleeping bag, all at an unbeatable weight!

Includes a Free Zpacks Roll Top Dry Bag for Storage! A $30 value!

You can also get a similar bag as a zipper-less Solo Quilt​, or as a Full-Zip​ version that includes a draft tube.

  • Constructed with responsibly sourced and 'Responsible Down Standard' certified DownTek PCF-FREE water-resistant 900 fill power goose down which stays dry 90% longer than untreated down.
  • Each compartment is overstuffed with 30% more 900 Fill Power Premium Goose Down than is necessary for maximum loft to account for any future down compression.
  • Vertical baffles on the upper body keep down from migrating to the sides. Tightly spaced compartments help keep the down evenly distributed so there are no cold spots. There are no "sewn through" seams.  
  • Our rectangular foot box is roomy, and fits the shape of your feet comfortably when lying on your side, on your stomach, or on your back with your feet angled out in a relaxed position. 
  • Black fabric on the inside for quick drying. Both the liner and the shell are treated with C0 durable water repellent to resist rain spray and body moisture. 
  • 3/4 Length Zipper extends to your calves. The zipper is positioned on the bottom of the bag allowing for multiple sleep set ups.
  • The bag can easily be opened up for venting in "quilt mode". Most of the time you probably won't even use the zipper.  
  • Since the zipper is underneath you no draft tube is necessary- that means less weight and much less chance of a frustrating zipper snag.  Getting in and out is as easy as turning the zipper to the side, or just slide in or out the top of the bag.
  • A flat clip at the top of the zipper keeps the zipper securely closed. Or use the clip alone with the zipper opened for venting.  
  • An Elastic cord can be cinched tight around your neck to keep out drafts, or pull the bag up around your ears. This bag does not have a hood- wear a warm hat, or a Goose Down Hood, or size up in length if you want to pull it up around your head.  
  • Roll Top Dry Bag is included, and adds ~.9 ounces (25.5 grams) to the listed weight. The dry bags are a comfortable fit and can be compressed smaller by squishing the contents and rolling the top down more.
  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.
  • Our sleeping bag shell materials do not contain any harmful chemicals such as flame retardants. Our shell is treated with C0 Durable Water Repellent, which is free of PFOA and PFOs

ISO Rating

While our sleeping bags and quilts have not been tested for their International Standard Organization (ISO) rating, we estimate based on feedback and use that they are closest to the  ISO "Transition Range.“

.51 oz/sqyd Ventum Ripstop Nylon

The inner and outer shells of our Sleeping Bags and Quilts are both made from this super light, high quality, 7 denier fabric that weighs in at just .51 oz/sqyd (17 g/m²). 

Featuring a high quality "C0" durable water repellant (DWR), this ripstop and tear resistant material can also handle light mist and dew (but is not waterproof).

Ventum nylon cuts the wind while still allowing for excellent vapor transfer and breathability. With a soft texture, Ventum is not sticky or plastic feeling like some other fabrics in this weight range.

The material is down and mosquito proof and is an excellent choice for wind shell clothing and sleeping bag shells.

Ventum fabric tests at 39.5 CFM under ASTM D-737.



DownTek 900 Fill Power Water Repellent Goose Down

DownTek 900 Fill power goose down has a "C0" water repellent which allows it to stay dry over 90% longer than untreated down. The water repellent is PFOA and PFOS free. It is 'Responsible Down Standard' certified, ensuring that the animals are treated humanely. Goose down is a byproduct of the goose meat industry.

Classic 30

I'm loving my sleeping bag so far. It packs up small enough to use in my Nero pack and keeps me cozy without having to compromise weight.

Pretty good

Very lightweight and compact with good dry sack included. Would question the comfort rating. Needed a liner and layers on a night warmer than 30F sleeping in a Z-packs duplex tent.

Excellent sleeping bag

Super effective. Used to have a quilt from a different brand, but didn’t like the draftiness. I got the wide regular of this bag and love it

Light, warm enough

I haven't had any cold nights where I knew the temperature exactly, but I think it's warm enough for the advertised temp. I'm an overweight side sleeper and the standard width still seems to be more than enough. At 5'11" I could have used an XL length option to get it completely over my head. I sometimes felt like I could have wanted the zipper to open a bit further, essentially to lie with my knees further apart yet both feet in the box. OTOH, I may not need a zipper at all. There could be an option for full length opening on the quilt. Oh, and the draw cord could use something to keep it out of my face. All in all, half the weight of my former sleeping bag and works just as well. Comfy to sleep in!
