Sea To Summit Spark -1C Down Sleeping Bag

The Sea to Summit Spark range of sleeping bags are ultralight high performance Down sleeping bags perfectly suited to lightweight backpacking, cycle touring and adventure racing. Their low bulk and lightweight materials result in an impressively small pack size so gram counters don't have to compromise on a comfortable nights sleep.

The ultralight 10D nylon outer and 10D liner ensure that the down inside the bag lofts fully. The Spark -1C uses box baffle construction at the top to accommodate extra down and reduce cold spots. The bottom half of the bag uses stitch through baffles to ensure a lightweight and very packable bag. The Down used in the Spark range is 850+FP responsibly sourced RSD ULTRA-DRY Down treated water repellent down. This protects the down from moisture and ensures a longer lifespan, it down not mean that the Down is waterproof.

The Spark -1C features a 1/2 length zip for easy access and extra ventilation options while keeping the overall weight down. The neck, zipper and hood feature draft collars to prevent your body's hard generated warmth being lost. The Mummy sizing is a little oversized to allow space for extra layers of clothing or some wriggle room if you're a restless sleeper.
