What Our Gearhead® Experts Are Saying: "The Spark 0F blows me away with how warm it is for the weight. The box-baffle construction and 850+ down loft give it legit winter performance without the bulk. The full-length zipper makes it far more livable than most ultralight winter bags, and the hood and footbox shed condensation incredibly well." We rely on the Sea to Summit Spark 0F when the trail leads into true cold and every ounce of warmth matters. Packed with lofty 850+ Ultra-Dry Down and wrapped in a 10D shell treated to repel condensation, this bag’s construction is tuned for high-efficiency warmth in freezing climates.
