Zpacks Summer Twin Quilt - is designed for couples who want to share warmth without carrying unnecessary weight. Providing just the right amount of insulation for summer nights with temperatures above 4 °C (40 °F), it offers a comfortable and efficient sleep system for warm-weather backpacking and camping.
Exceptionally lightweight and compact, this quilt is easy to pack even into a daypack and helps maintain an impressively low base weight on longer adventures.

Its spacious design allows two people to sleep comfortably while sharing body heat, making it an efficient alternative to carrying two separate sleeping bags.
For some couples, the quilt can also be used in colder conditions approaching freezing, especially when combined with additional layers such as a Zpacks Down Jacket and an Octa Fleece Hat, and by benefiting from the shared warmth of sleeping together.

Zpacks includes a Medium DCF Roll Top Dry Bag (valued at $40), which offers compact and efficient storage. In addition, we will also include a large mesh storage bag for storing your quilt at home, helping maintain its loft and performance over time.

Constructed from responsibly sourced 900 fill power water-resistant DownTek, certified by the Responsible Down Standard (RDS), the quilt is overstuffed by 30% for maximum loft and long-term performance. The design features vertical baffles on the upper body to prevent down migration, ensuring even distribution and eliminating cold spots. An envelope-style foot box provides comfort in various sleeping positions, and the black fabric interior aids in quick drying. Both the liner and shell are treated with PFC-Free durable water repellent, making them resistant to rain spray and body moisture.

The quilt’s fabric is made from Ventum Ripstop Nylon, a lightweight, high-quality material that offers excellent wind resistance, breathability, and a soft texture. It is also down and mosquito-proof, making it an excellent choice for sleeping bag shells. This durable fabric ensures long-lasting performance without the use of harmful chemicals.
