Sea To Summit Spark Ultralight 7°C Sleeping Bag (Long)

The Spark Ultralight Mummy Sleeping Bag Series spans everything from an ultralight down-filled liner to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and no-frills design to provide cutting-edge performance.

The Spark Ultralight 7 Degrees Sleeping Bag has been created with an 850+ Fill Power, RDS-certified, Goose Down with Ultra Dry Down treatment for improved water resistance in damp conditions. The Down works to trap heat in small air pockets and retain warmth, keeping you toasty when the temperatures drop. The sleeping bag uses box wall baffles for the top half, including vertical chest baffles and horizontal baffles on the lower half and base with a sewn-through quilted construction. Increasing the bag's durability is a 10-denier Nylon shell and lining fabric. These lightweight fabrics offer breathability, protection and effective temperature regulation for premium comfort outdoors. Also, the outer fabric is waterproof and breathable, offering protection and preventing exposure to tent wall condensation. To increase heat retention and comfort a fitted front draft collar has been included and is scalloped over the neck and oversized at the shoulders, providing additional room. The sleeping bag has multiple zips for easy on/off whilst increasing ventilation in areas you need it most. With a mummy cut with a generous foot box and technical hood, the sleeping bag maximises thermal efficiency and minimises bulk and weight. Finishing the sleeping bag is a STS QuiltLock system that lets you attach a Sea To Summit quilt effortlessly for extra comfort.
