Key Features
- Ultra Lightweight & Compact Design: Weighing just 2.16 lbs with the built-in pillow, this mummy-style sleeping bag uses only 14.11 oz of down fill to maximize warmth while minimizing bulk. It compresses neatly into its included compression sack to a compact 11.8 x 6.29 inches—perfect for fitting snugly into backpacks without sacrificing valuable space during long hikes or international travel.
- Premium 680FP Traceable White Duck Down Fill: At the heart of this sleeping bag lies ethically sourced, high-fill-power down rated at 680FP. This premium material provides superior insulation with minimal weight, offering reliable warmth across a broad temperature spectrum. Under normal conditions, it performs well between 32°F and 45°F, and can handle extreme cold as low as 20°F thanks to its high loft and efficient heat retention. For those venturing deeper into sub-freezing environments, a lighter 1.76 lb version is available, optimized for temperatures from 5°F to 23°F.
- Practical, Thoughtful Design Elements: Every detail has been carefully considered for real-world use. The two-way zipper includes an interior pull tab for one-handed operation, making it easy to get in and out of the bag or ventilate on warmer nights. Two bags can be zipped side-by-side to create a spacious double bed—ideal for couples or anyone who prefers extra room. An inner chest pocket keeps phones, headlamps, or small essentials within reach throughout the night. The adjustable hood features a drawcord with reflective stripes, sealing in warmth while enhancing nighttime visibility for safety during emergencies.
- Durable, Soft, and Weather-Resistant Construction: The outer shell is made from 400T 40D tear-resistant nylon that repels moisture and stands up to abrasion from rough terrain or campfire setups. Inside, the breathable Pongee lining feels soft against your skin, preventing irritation during extended use. A reinforced chest collar adds targeted insulation where you need it most, ensuring comfort even when temperatures drop unexpectedly.

Benefits & Use Cases
This sleeping bag excels in scenarios where every gram matters—whether you’re covering hundreds of miles on a thru-hike or setting up camp after a full day of trail exploration. Its mummy shape reduces dead air space, helping retain body heat more efficiently than rectangular designs, which is especially valuable in windy or cold conditions. The integrated pillow eliminates the need for bulky external gear, saving both weight and setup time. For families or groups, the ability to connect two bags creates a comfortable shared sleeping area without doubling your load. Teenagers heading off to scout camp, parents planning weekend trips, or seasoned hikers upgrading their kit will appreciate how seamlessly this bag fits into diverse outdoor lifestyles.
Thanks to its durable materials and weather-resistant shell, this sleeping bag holds up well in changing climates—from damp morning dew to unexpected rain showers. While the down fill performs exceptionally when dry, proper care ensures longevity: always store it in a breathable stuff sack or loose in a dry place, and never expose it to prolonged moisture. A waterproof cover is recommended for extended wet-weather use.

Important Notes
To maintain optimal performance, store this sleeping bag in a cool, dry environment away from direct sunlight and dampness. Avoid compressing the down fill for extended periods; instead, periodically airing it out helps restore loft and insulation efficiency. While the shell resists light moisture, prolonged exposure to rain or humidity may compromise down performance—always pair with a waterproof cover if needed. The product comes with a compression sack for transport, though no additional stuff sack is included. Customer inquiries are addressed promptly by our localized support team, with responses typically provided within one hour and no later than eight hours.
