Our Summer Quilt is designed with just the right amount of warmth for summer nights when the forecast is 40F (4C) or above. This bag is so light, and packs down so small it can easily be tucked in your day pack just in case, or achieve an unbeatable base weight on longer summer trips.

Combine this quilt with our Zpacks Goose Down Jacket and a Fleece Hat to boost the warmth even further when needed.

The summer quilt closes with a snap at the center and at the neck for easy venting on hot nights. Shock cord can be cinched at the neck to seal out drafts.

The Summer Quilt is also compatible with our Sleeping Pad Quilt Strap (sold separately) which allows you to snap it to your sleeping pad to keep it tucked and in place.

When freezing weather rolls around the Summer Quilt springs back into action as a Winter Liner. It works well as an additional layer to push the limits of your three season sleeping bag further into the colder seasons. It fits well inside any of our bottom zipper or side zipper sleeping bags, quilts, and mummy bags.

If you can only own two sleeping bags, combine one of our 20F (2.5" loft) bags and this (1.25" loft) Summer Quilt / Winter Liner to keep you comfortable nearly year round by layering as needed.

A Zpacks Slim DCF Roll Top Dry Bag is included! A $30+ value!

  • 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.
  • This bag features an envelope style foot box that 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. Sewn through seams keep the weight to a minimum.
  • Black fabric on the inside for quick drying. Both the liner and the shell are treated with PFC-Free C0 durable water repellent to resist rain spray and body moisture. 
  • The quilt has a snap at the center to help keep the sides secured underneath you. A Sleeping Pad Quilt Strap can be added if desired to keep the sides tucked and in place.
  • A snap at the top keeps the bag securely closed at the neck.
  • 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 Fleece Hat, a Zpacks Down Jacket w/ a hood, or size up in length if you want to pull it up around your head.  
  • A Slim Dry Bag is included, and adds ~.6 ounces (17 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.
