About the Sea to Summit Spark - 1C Regular

Experience the pinnacle of ultralight comfort and performance with the Spark -1C Ultralight Mummy Sleeping Bag. Whether you're embarking on a multi-day trek through rugged terrain or seeking refuge under the starlit sky, these sleeping bags are designed to enhance your outdoor adventures.

Everything about the Spark Ultralight has been engineered to deliver optimum warmth without the weight penalty. A mummy shape and ultra lightweight 10D nylon shell deliver a low bulk sleeping bag with a compact design and packed weight of just 493g.

Ultra-Dry Down 850+ fill power insulation gives you a highly compressible goose down with water-repellent treatment that protects from both external moisture and internal condensation. This helps retain loft and absorb less moisture when compared with untreated down and continues to insulate even in damp conditions. An adjustable hood and generous footbox round out the design to deliver optimum warmth and comfort.

The Spark -1C is crafted with premium materials and a streamlined design, ensuring unparalleled performance in any environment. Snug enough to maximize thermal efficiency, yet spacious for unrestricted movement during those epic hikes and treks.
