Product Overview
This Naturehike Ultralight Backpacking Sleeping Bag is designed for adults who seek a reliable, lightweight, and warm sleeping solution for outdoor adventures. Ideal for backpackers, campers, and hikers, it delivers exceptional warmth-to-weight performance thanks to its high-quality 650 fill power duck down and thoughtful engineering. Whether you’re exploring grasslands, mountains, or deserts under the stars, this sleeping bag offers compact portability and durable comfort across three seasons. Its professional-grade construction makes it suitable for both beginners and experienced outdoor enthusiasts.
Key Features
- Sufficient Down Filling: The sleeping bag is filled with 295g of premium duck down, ensuring generous insulation that traps warm air effectively. This results in a thick, enveloping feel that keeps you cozy without excess weight. The naturally odorless down and high 650 fill power create an exceptionally fluffy texture, offering a cloud-like comfort experience. Before first use, gently tap the bag to restore loft and maximize warmth.
- Individual Down Channel Design: Each chamber is independently segmented to prevent down from shifting or clumping. This design ensures even heat distribution and consistent warmth around your entire body, enhancing overall comfort during sleep. It’s engineered to deliver a reliable thermal experience whether you’re sleeping on cold ground or in variable weather conditions.
- Ultralight and Compact: Weighing just 1.3 lbs (565g)—comparable to a standard water bottle—this sleeping bag is incredibly lightweight for easy carrying. When packed, it measures Φ4.7″ x 10.2″ L (12 x 26 cm), making it highly stowable in any backpack. You can even remove it with one hand using the included organizer, allowing quick setup at campsites or spontaneous rest stops.
- Premium Quality Materials: Constructed with 20D400T insulated nylon fabric and lining, the sleeping bag is both wear-resistant and soft to the touch. The fabric features a water-repellent treatment that protects against moisture, while the durable material ensures long-term usability. A YKK two-way zipper allows for zipping two bags together into a double configuration and resists snagging. Additional details include lint-free Velcro for securing the hood and a highly elasticized stowage opening that helps retain heat near the neck.
- Professional Entry-Level Performance: Recognized as Naturehike’s most popular entry-level down sleeping bags, the CW295 and CWM400 models are trusted by outdoor users worldwide. They balance affordability with high-end features, making them perfect for those new to backpacking or seasoned adventurers looking for a dependable backup.
