Crafted with premium materials, this sleeping bag ensures optimal warmth without adding excessive weight to your backpack. The use of high-quality fabrics and insulation allows for a lighter load while maintaining excellent performance.

Temperature rating and insulation

The Parsec 0 is designed to provide comfort and warmth in cold weather conditions. With a temperature rating of 0 degrees Fahrenheit (-18 degrees Celsius), this sleeping bag is suitable for chilly nights in the great outdoors. Its insulation technology, such as the eraLoft™ synthetic insulation, efficiently retains body heat, ensuring a cozy and restful sleep.

Comfort and fit

Comfort is paramount when it comes to a good night’s sleep while camping. The Parsec 0 offers a spacious and ergonomic design that allows for unrestricted movement inside the sleeping bag. Its footbox design provides extra space for your feet, reducing discomfort and enhancing overall comfort. Additionally, the sleeping bag features a draft collar and draft tubes that help seal in warmth and prevent cold air from entering.

Durability and weather resistance

Outdoor adventures can be demanding, and your sleeping bag should be able to withstand rugged conditions. The Parsec 0 is built to last, thanks to its durable construction and rugged materials. The outer shell is made from ripstop nylon, which enhances the sleeping bag’s durability and resistance to tears. Furthermore, the DWR (Durable Water Repellent) coating on the shell protects against moisture, ensuring a dry and comfortable sleep even in damp environments.

Packability and ease of transportation

For backpackers and hikers, having a sleeping bag that is easy to pack and carry is essential. The Parsec 0 excels in this aspect, as it can be compressed into a compact size, making it convenient for long hikes and backpacking trips. Its lightweight nature also contributes to the ease of transportation, allowing you to carry it without excessive strain on your back.

Insulation technology and warmth retention

With its advanced eraLoft™ synthetic insulation, the Parsec 0 provides excellent warmth retention, even in cold weather conditions.

This technology keeps you cozy and comfortable throughout the night, allowing you to wake up refreshed and ready for the day ahead.

Ventilation and moisture management

Maintaining a comfortable temperature inside a sleeping bag is crucial to a good night’s sleep. The Parsec 0 incorporates ThermaCapture™ seams, which trap radiant body heat and prevent it from escaping. At the same time, the bag’s breathable materials allow excess heat and moisture to escape, reducing condensation and ensuring a dry and comfortable sleeping environment.
