Discover the pinnacle of ultralight warmth and versatility with the SEA TO SUMMIT Spark Pro -1°C Sleeping Bag. Engineered for fast-and-light adventurers who refuse to compromise on comfort, this bag offers an unparalleled sleep experience, from chilly alpine bivouacs to extended backcountry treks. Its design ethos centers on providing maximum thermal efficiency in a minimalist, highly compressible package, making it the definitive choice for alpinists, bike packers, and serious backpackers. This is not just a sleeping bag; it´s a technical piece of equipment designed to push your boundaries in the great outdoors.
The SEA TO SUMMIT Spark Pro -1°C Sleeping Bag in Grey/Black is a high-performance sleeping bag designed for cold weather camping and backpacking. It features 850-fill down insulation, which provides incredible warmth without adding extra bulk. The mummy shape helps to trap body heat and minimize cold spots, while the contoured hood and draft collar help to seal in warmth. The bag has a temperature rating of -1°C, making it suitable for chilly nights in the backcountry. The lightweight and compressible design make it easy to pack and transport, making it a great choice for those seeking a high-quality, warm sleeping bag for their outdoor adventures.
The true innovation of the Spark Pro lies in its adaptable Free-Flow zip system. This unique configuration includes a full-length main side zipper, a half-length zipper on the opposite side, and a third zipper in the footbox. This system grants you ultimate freedom and temperature regulation. Keep it fully zipped for maximum warmth in a snug mummy configuration on the coldest nights. On milder evenings, open both side zippers to fold down the top section like a quilt, freeing your arms. You can even open the footbox zip for ventilation, creating a truly customizable sleep environment for any condition within its 5 to -5 °C comfort range.
Key Benefits & Features:
* Exceptional Warmth-to-Weight: Utilizes premium 850+ fill-power insulated down to deliver incredible loft and thermal performance while keeping pack weight to an absolute minimum.
* Unmatched Versatility: The innovative Free-Flow triple-zip system allows the bag to be transformed from a technical mummy bag into a spacious quilt, offering multiple ventilation and comfort options.
* Optimized Thermal Efficiency: A contoured mummy shape minimizes dead air space, while an adjustable technical hood, oversized zipper draft tube, and draft collar work in unison to lock in heat and prevent cold drafts.
* Advanced Insulation Mapping: Vertical baffles on the chest prevent the down from migrating or shifting during the night, while horizontal baffles in the lower half provide targeted warmth. The design ensures the premium insulation stays where you need it most.
* Ultralight & Packable: Constructed with advanced, incredibly lightweight shell and liner fabrics that allow the bag to compress to an impressively small size, freeing up valuable space in your pack.
* Unisex Performance Fit: Designed as an adult sleeping bag for both men and women, it offers a comfortable yet efficient fit that provides more room around the hips and knees than traditional mummy bags, allowing for multiple sleep positions.
