The Spark Pro -9ºC redefines what´s possible, offering a perfect balance of insulation, minimal packed size, and versatile functionality.
Designed for both men and women, this adult sleeping bag provides a thermally efficient yet surprisingly spacious sanctuary after a long day on the trail. Its innovative design allows you to push your boundaries, ensuring you stay warm and comfortable down to freezing temperatures, so you can rest, recover, and be ready for the next day´s objective.
Key Benefits:
* Exceptional Ultralight Warmth: Achieve incredible insulation with a minimal weight footprint. The premium 900+ Loft fill power delivers an outstanding warmth-to-weight ratio, keeping you protected from the cold without weighing down your pack.
* Unmatched Versatility: Adapt to changing temperatures with the revolutionary Free-Flow Zip system. A full-length main side zipper, a half-length opposite side zipper, and a footbox zipper allow you to open the bag into a full quilt for milder nights or precisely manage ventilation.
* Superior Weather Resistance: Don´t let damp conditions compromise your warmth. The high-performance insulation is treated to be highly water-repellent, maintaining its loft and thermal efficiency even when exposed to moisture. Combined with an ultralight, water-resistant shell, you get reliable protection from condensation and frost.
* Thermally Efficient Design: The contoured mummy shape minimizes dead air space to maximize thermal performance, while the advanced baffle construction—vertical baffles on the torso and horizontal baffles on the lower half—prevents insulation from shifting and eliminates cold spots.
Main Features:
The Spark Pro is packed with technical features designed for the discerning user. A full-length draft tube along the main zipper and a snug-fitting draft collar work in tandem to seal in warmth and prevent precious heat from escaping. The technical hood cinches down securely around your head, providing critical insulation on the coldest nights. The Free-Flow Zip system not only offers temperature regulation but also provides freedom of movement, allowing you to stick your arms out while remaining cozy inside the bag. Every detail, from the ultralight shell and liner fabrics to the carefully mapped insulation, is optimized for performance in the mountains.
